Answer:
(a) The total combined paint is 10.3L
(b) 8.8L paint was left after painting
Step-by-step explanation:
From the question, John combines 7L of white paint with 3300 milliliters of blue paint.
First, convert to the same unit, say liters, L.
Now, we will convert 3300 milliliters to liters (L)
{NOTE: 1000 milliliters (mL) = 1 liter (L)}
Since 1000 milliliters = 1 liter
∴ 3300 milliliters = 3300/1000 liters = 3.3 liters
Hence, 3300 milliliters = 3.3 L
Therefore, he combines 7L of white paint with 3.3L of blue paint.
(a) The total combined paint is 7L + 3.3L = 10.3L
∴ The total combined paint is 10.3L
(b) To determine how much paint was left after painting,
From the question, he uses 1 ½ L of paint to paint a hallway, that is, he uses 1.5 L of paint to paint a hallway;
The paint left will be 10.3L - 1.5L
10.3L - 1.5L = 8.8L
Hence, 8.8L paint was left after painting
Use the graph to determine which statement describes f(x)
O A. f(x) does not have an inverse function, because its graph fails the
horizontal line test.
O B. f(x) has an inverse function, because its graph passes the
horizontal line test.
C. f(x) has an inverse function, because its graph passes the vertical
line test.
D. f(x) does not have an inverse function, because its graph fails the
vertical line test.
Answer:
f(x) does not have an inverse function, because its graph fails the horizontal line test. ⇒ A
Step-by-step explanation:
The vertical line test is used to show that the graph represents a
function or not
If the vertical line crosses the graph in more than one point, then the graph does not represent a functionIf the vertical line crosses the graph in only one point in different positions, then the graph represents a functionThe horizontal line test is used to show that the function has an
inverse or not
If the horizontal line crosses the graph of a function in more than one point, then the function has no inverseIf the horizontal line crosses the graph of a function in only one point in different positions, then the function has an inverseLet us look at the given graph
→ The graph represents a parabola, which represents the function f(x)
∵ Any horizontal line drawn will cross the graph in more than one point
∴ f(x) has no inverse
∴ f(x) does not have an inverse function, because its graph fails the
horizontal line test.

6x + 9 =27 (I need help please )
Answer:
X=3
Step-by-step explanation:
6x=27-9
6x=18/6
x=3
Answer:
x=3
Step-by-step explanation:
Alrighty lets begin.
First, subtract 9 from 9 and from 27. Your equation will look like:
6x=18
Now, divide 6 from 6x and from 18. It would look like:
6x/6 = 18/6
Then cancel out the 6's.
And finally, simplify 18/6 and you get 3.
Your answer is x = 3

Twice a number y is no more than 12.
can someone help me on this please? i just need the work and answer for balancing the equation
Answer:
Step-by-step explanation:
2x - 8 = 10
Bringing like terms on one side
2x = 10 + 8
2x = 18
x = 18/2 = 9
Answer:
x= 9 balance the equation
Step-by-step explanation:
2x-8=10 -------- equation (1)
2x=10+8 -------- equation (2)
2x=18
x = 9
let's put x = 9 into equation(2)
2(9) =10+8
18=18, x= 9 balance the equation
Jack's family left home at 9:00 AM and drove to the amusement park at 60 mph. They spent 7 hours at the park and then drove back home. On the way home, traffic was bad and they drove 20 mph slower than in the morning. They got home at 8:00 PM. How far is the amusement park from Jack's home?
Answer:
96
Step-by-step
the distance from the amusement to jack's home is x (mile, x>0)
jack's family went to the amusement park at: 9 + x/60
On the way home, traffic was bad and they drove 20 mph slower than in the morning⇒ they drove: 60 - 20 = 40 mph
they left the amusement park at: 20 - x/40
have the following equation:
(20 - x/40) - (9+ x/60) = 7
⇔ 4 = x/40 + x/60
⇔ x = 96
so the distance from the amusement park to jack's home is 96 mile
Distance of amusement park from Jack's home = 96 miles
Let the distance from Jackie's house to the amusement park be x.She drove at a speed of 60 mph to get to the amusement park.
Now, formula for time is;Time = distance/speed
Time; t1 = x/60 hours
Now, we are told she spent 7 hours at the park. Thus; t2 = 7 hoursOn her way back home from school, we are told she drove 20 mph slower than her speed in the morning. Thus, speed = 60 - 20 = 40 mphThus; time; t3 = x/40
Now, she left home by 9 am and got home by 8pm same day. This is a total of t = 11 hoursThus;
t1 + t2 + t3 = 11
Plugging in the relevant values;
(x/60) + 7 + (x/40) = 11
Rearrange to get;
(x/60) + (x/40) = 11 - 7
(x/60) + (x/40) = 4
Multiply through by 120 to get
2x + 3x = 480
5x = 480
x = 480/5
x = 96 miles

Please help! I need help on the whole worksheet
In this figure ∠7 and ∠3 are alternate interior angles . Alternate interior angles in two parallel lines with a transversal will always be equal . Since ∠7 is congruent to ∠3 , we can say that line m and line n are parallel lines .
Therefore :-
The lines are parallel because the alternate interior angles in them are congruent .
Solution (2) :-Given :-
m∠3 = ( 15x + 22 )°
Then , m∠3 will be equal to :-
x = 8
= 15 × 8 + 22
= 120 + 22
m∠3 = 142°
m∠1 = ( 19x - 10 )°
= 19 × 8 - 10
= 152 - 10
m∠1 = 142°
angle 1 and angle 3 are corresponding angles , which means their value will be equal if they are present on two parallel lines with a transversal . As their values are equal we can say that line m and line n are parallel .
Therefore :-
Yes , the lines are parallel because the corresponding angles in them are equal .
Solution (3) :-∠7 and ∠6 are interior angles on the same side of transversal , which means their angle su, will be equal to 180° . But since their values are equal these two lines are not parallel .
Therefore :-
∠7 and ∠6 are interior angles on the same side of transversal , so their sum will be equal to 180° . But since that is not the case in the lines shown above , those lines are not parallel lines .
Solution (4) :-Given :-
m∠2 = ( 5x + 3 )°
x = 14
= 5 × 14 + 3
= 60 + 3
= 63°
m∠3 = ( 8x - 5 )°
= 8 × 14 - 5
= 112 - 5
= 107°
We know that the sum of angle 2 and angle 3 will be equal to 180° if they are on two parallel lines as they are interior angles on the same side of transversal .
As :-
∠2 + ∠3 ≠ 180°
63° + 107° is not equal to 180° ,
Therefore :-
These lines are not parallel as the sum of their interior angles on the same side of transversal is not equal to 180°.
Solution (5) :-Given :-
m∠8 = ( 6x - 1 )°
x = 9
= 6 × 9 - 1
= 54 - 1
= 53°
m∠4 = ( 5x + 3 )°
= 5 × 9 + 3
= 45 + 3
= 48°
angle 8 and angle 2 are vertically opposite angles , which means m∠8 = m∠2 .
m∠2 = 53°
As ∠2 and ∠4 are corresponding angles their value will be equal , if they are on parallel lines .
Since angle 2 , angle 8 and angle 4 are not equal these lines are not parallel lines .
Therefore :-
The lines are not parallel as their corresponding angles are not equal .
Solution (6) :-Angle 5 and angle 7 are corresponding angles they will be congruent when on parallel lines .
As , m∠5 ≅ m∠7 these lines are parallel .
Therefore :-
These lines are parallel lines as their corresponding angles are equal .
Solution (7) :-Angle 1 and angle 7 are vertically opposite angles , which means their angle measure will be equal . As angle 7 and angle 5 are corresponding angles their angle measure will also be equal .
Since m∠5 ≅ m∠7 , these lines are parallel .
Therefore :-
These lines are parallel lines as their corresponding angles are equal .
Solution (8) :-Here , the value of x is the same .
Which means :-
m∠2 = x + 15° is greater than m∠6 = x + 10°
Angle 2 and angle 6 are alternate interior angles , their values should be equal . But since their values are not equal , the lines on which they reside are not parallel .
Therefore :-
These lines are not parallel as their alternate interior angles are not equal .
Solution (9) :-It is given that angle 1 and angle 3 are supplementary angles . It is also clear that angle 1 and angle 2 are a linear pair , which means their angle sum will be equal to 180° . Also , angle 3 and angle 2 should be equal since they are the supplement of the same angle . Angle 2 and angle 3 are also corresponding angles . Since corresponding angles in two lines with a transversal will be equal and in these two lines the corresponding angles are equal , these lines are parallel lines.
Therefore , JK // HI as their corresponding angles are equal .

7. Mark needs to move to a new apartment and is trying to find the most affordable moving truck. He will only need to truck for one day. After checking the U-Haul website, he finds that he can rent a 10 - ft truck for $20.95 a day plus $1.89 per mile. He then checks the Public Storage website and finds the charge to be $37.95 a
day plus $1.19 per mile for the same size truck. Determine the number of miles for which the cost to rent from either company would be the same. Round the answer to the nearest mile (5 points).
Answer:
24 miles
Step-by-step explanation:
Let the number of miles = x.
U-Haul:
1.89x + 20.95
Public Storage:
1.19x + 37.95
Set the costs equal and solve for the mileage, x.
1.89x + 20.95 = 1.19x + 37.95
0.7x = 17
x = 24.29
Answer: 24 miles

determine if the equation is true x = 8
2x - 6 = 9
Answer:
False
Step-by-step explanation:
This is false because:
1) In order to solve this, we cam use the addition property of equality
2) First, you can add 6 to -6 and 9
New Equation: 2x = 15
3) Now divide 2 with 2 and 15
New Equation: x = 7.5
You can also check by inserting 8 into the equation.
2(8) - 6 = 9
16 - 6 = 9, this is not true.
Therefore, this statement is false. x = 7.5

7(x - 3) = 4(x + 5)
HELP ASAP
Step-by-step explanation:
7(x - 3) = 4(x + 5)
7x - 21 = 4x + 20
3x = 41
x = 13.67
Let's solve your equation step-by-step
7(x-3)=4(x+5)
Step 1:Simplify both side of the equation
7(x-3)=4(x+5)
(7)(x)+(7)(-3)=(4)(x)+(4)(5) (Distribute)
7x+-21=4x+20
7x-21=4x+20
Step 2:Subtract 4x from both sides
7x-21-4x=4x+20-4x
3x-21=20
Step 3: Add 21 to both sides
3x-21+21=20+21
3x=41
Step 4: Divide both sides by 3
3x/3 =41/3
Answer: x=41/3
