Answer:
y=0.75m+45
Step-by-step explanation:
when you bought the car it was 45, that doesnt change so its a constant
but every mile you drive, it changes, therefore it becomes the dependent or the rate :)
so we just make it into an equation of
y=0.75m+45
where y= the total amount of money owed
and if you wanted to solve for how far the car drove, plug in the 222.5 in for y, as that was the amount owed and solve!
222.5=0.75m+45
177.5=.75m
now divide by .75
m= 236 2/3 miles
hope this helped :))

Find the value of x.
x=
Answer:
x = 14
Step-by-step explanation:
These angles are complementary angles, meaning they have a sum of 90°.
4x + 1 + 2x + 5 = 90
6x + 6 = 90 (Added like terms.)
6x = 84 (Subtracted 6 on both sides.)
x = 14 (Divided 6 on both sides.)
[tex]\sf \longmapsto \: (4x + 1) + (2x + 5)[/tex]
It has a sum of 90 as the given angles are complementary angles.[tex]\sf \longmapsto \: 4x + 1 + 2x + 5 = 90[/tex]
[tex]\sf \longmapsto4x + 2x + 1 + 5 = 90[/tex]
[tex]\sf \longmapsto6x + 6 = 90[/tex]
[tex]\sf \longmapsto6x = 90 - 6[/tex]
[tex]\sf \longmapsto \: 6x = 84[/tex]
[tex]\sf \longmapsto \: x = \cancel\dfrac{84}{6} [/tex]
[tex]\sf \longmapsto \: x = 14[/tex]

2(x+3)=x-4
Anyone know the answer please lol
Answer:
The Answer is -10.mark this answer as BRAINLIEST answer. And I hoped this helpful for you....
Thank you ☺️☺️
Lets solve your equation step-by-step
2(x+3)=x-4
Step 1 :Simplify both sides of the equation
2(x+3)=x-4
(2)(x)+(2)(3) =x+-4 (distribute)
2x+6=x+-4
2x+6=x-4
Step 2: Subtract x from both sides
2x+6-x=x-4-x
x+6=-4
Step 3: Subtract 6 from both sides
x+6-6=-4-6
Answer: x=-10

If you travel 1000 feet in 5 minutes, what is your speed per minutes?
Answer: 200 feet
Step-by-step explanation:
1000feet/5feet= 200feet
Answer:
200 feet per minute
Step-by-step explanation:
Speed = Distance/Time
Since you want to find the "per minute", you would just divide the total distance by the number of minutes:
1000 feet / 5 minutes = 200 feet per minute

Solve 5x − 2(2x − 1) = 6
Answer: x = 8
Step-by-step explanation:
The answer begins with the distributive property, multiplying positive 2 times the elements in parenthesis.
5x - (2)(2x - 1) = 6
5x - 4x - 2 = 6
1x = 6 + 2
x = 8
The slope is 3 true or false?
Answer:
The slope IS NOT 3.
So the statement is FALSE.
Step-by-step explanation:
y = mx + b
If we change the graph shown into the format shown above it would be:
y = 1x - 3
mx = slope
Slope = 1x
b = y-intercept
b = -3
To find the slope you must do:
[tex]\frac{y}{x} =\frac{RISE}{RUN}[/tex]
y = rise
x = run
In the graph shown, the points are going up and shift to the right 1 unit.
So the slope is: 1x
Therefore, the statement, "The slope is 3" is actually false.
Find the slope of
(-16,3), (13,8)
Answer:
= 5/29
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 8-3)/(13 - -16)
= ( 8-3)/( 13+16)
= 5/29
Solving a linear equation: Your hourly wage is $9.75 per hour plus
$0.80 for each unit you produce. How many units
must you produce in 1 hour so that your hourly wage
is $19.35?
Answer:
You must produce 12 units
Step-by-step explanation:
19.35 - 9.75=9.60
9.6/0.8=12
Answer:
the answer is 12 units
Step-by-step explanation:
u get 9.75 an hour and 0.80 for every unit so subtract 9.75 from 19.35 and u get 9.60 now divide that by 0.80 and u get 12 units
Basic math equations and calculations play an important role in many jobs tasks. If you were working at a grocery store and your cash register was not automatically calculating the 20% off sale on someone's cereal--how would you solve this issue from the options listed below? If the cereal was normally $2.88, I would... 1 point Take $2.88 and times it by 80 for a sale price of $2.30. Subtract $0.20 for a sale price total of $2.68. Divide 20 from $2.88 for a sale price total of $0.15.
Given :
Price of cereal without off, C = $2.88 .
Percentage off, P = 20% .
To Find :
Price after applying 20% off.
Solution :
Final price = Initial price - 20 % of initial price
[tex]F = 2.88 - 2.88\times \dfrac{20}{100}\\\\F=2.88-0.576\\\\F=\$ 2.304[/tex]
Therefore, final price after sale is $2.304 .
Hence, this is the required solution.

Triangle ABC has the following vertices:
A(1,9)
B(11,-7)
C(-9,3)
Is triangle ABC a right triangle, and why?
Choose 1 answer:
A) Yes, because AB I AC.
B) Yes, because of AB I BC.
C) No because AB is longer than AC.
D) No, because AABC doesn't have a pair of perpendicular sides
Answer:
Triangle ABC is not a right triangle because d) it doesn't have a pair of perpendicular sides
Step-by-step explanation:
Perpendicular sides mean that the slopes are "opposite reciprocals" of each other.
Example: slope is 1/2 and the perpendicular line's slope is -2
How? 1/2 changes to 2 (you flip it, reciprocal), and then from 2 to -2 (apply opposite sign)
So when you calculate the slopes of AB, AC, and BC, none of their slopes are opposite reciprocals of each other. You can calculate the slopes of each and compare them if you want to check.
I really hope this helps, do you think you can tell me if you got the answer correct? I'd feel really bad if you got it wrong because of me. All I know is that it's not a right triangle.

The sum of 4 times a number and 7 equals 5.
Use the variable w for the unknown number.
Answer:
4w +7 = 5
Step-by-step explanation:
Have a nice day.
Answer:
4w + 7 = 5
Step-by-step explanation:
"sum" means addition (+), so we're to add two items:
item 1 to be added
"4times a number" means multiplication(x) of 4 and w(because w stands for the unknown number).
Therefore, 4 x w = 4w
item 2 to be added
This is the number 7
The sum
4w + 7
Now, the sum, equals(=) the number 5, therefore answer:
4w + 7 = 5
what ordered pair would describe each intersection?
y=8-X and y=5X-40
Answer:
(8, 0 )
Step-by-step explanation:
Given the 2 equations
y = 8 - x → (1)
y = 5x - 40 → (2)
Substitute y = 5x - 40 into (1)
5x - 40 = 8 - x ( add x to both sides )
6x - 40 = 8 ( add 8 to both sides )
6x = 48 ( divide both sides by 6 )
x = 8
Substitute x = 8 into either of the 2 equations and solve for y
Substituting into (1)
y = 8 - 8 = 0
Solution is (8, 0 )

The dimensions of a rectangular monitor screen are such that it's length is 5 in. More than it's width. If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in^2. What are the length and width of the screen?
Given:
Length of a rectangular monitor screen is 5 in more than it's width.
If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².
To find:
The length and width of the screen.
Solution:
Let width of the screen be x inches.
Length of a rectangular monitor screen is 5 in more than it's width. So,
Length of screen = (x+5) inches
Area of screen is
[tex]Area=length\times width[/tex]
[tex]A_1=(x+5)\times x[/tex]
[tex]A_1=x^2+5x\text{ in}^2[/tex]
If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².
New length = 2(x+5) inches
New width = (x-1) inches
So, new area is
[tex]A_2=2(x+5)(x-1)[/tex]
[tex]A_2=(2x+10)(x-1)[/tex]
[tex]A_2=2x^2+10x-2x-10[/tex]
[tex]A_2=2x^2+8x-10 \text{ in}^2[/tex]
Area increased by 170 in².
[tex]A_2-A_1=170[/tex]
[tex](2x^2+8x-10)-(x^2+5x)=170[/tex]
[tex]2x^2+8x-10-x^2-5x=170[/tex]
[tex]x^2+3x-10=170[/tex]
Subtract 170 from both sides.
[tex]x^2+3x-10-170=0[/tex]
[tex]x^2+3x-180=0[/tex]
Splitting the middle term, we get
[tex]x^2+15x-12x-180=0[/tex]
[tex]x(x+15)-12(x+15)=0[/tex]
[tex](x+15)(x-12)=0[/tex]
[tex]x=-15,12[/tex]
Width cannot be negative. So, x=12.
Width = 12 inches
Length = 12+5 = 17 inches
Therefore, the length of screen is 17 inches and width is 12 inches.
