Answer:
x = 5
Step-by-step explanation:
1. Distributive Property
(Do what's in the parenthesis first)
4x - 2x + 6 = -4 + 5x - 5
2. Combine Like Terms
2x + 6 = -9 + 5x
3. Take away 6 on both sides
2x + 6 - 6 = -9 - 6 +5x
It will give u.....
2x = -15 + 5x
4. Subtract 5x on both sides
2x - 5x = -15
It will give u.....
-3x = -15
5. Divide by -3 on both sides to isolate the variable
-3x / 3 = -15/-3
Now you get....
x = 5
2 negatives make a positive
Thats ur answer
Hope this helped!

Step-by-step explanation:
n f(x) = -3x+4, find f(-2)
Answer: f(-2) = 10
Step-by-step explanation:
To fin f(-2), we must plug -2 in for x
y = -3x + 4
y = -3 (-2) + 4 = 6 + 4 = 10
Solve the x.
1. 11x + 9 = 40 - 47
2. 2x – 8 - 6x = 90
3. 5 (3x – 4) = x+6+ 12x
At the end of a snow storm, Michael saw there was a lot of snow on his front lawn.
The temperature increased and the snow began to melt at a steady rate. The depth of
snow on Michael's lawn, in inches, can be modeled by the equation S = - 2t +20,
where t is the time, in hours, after the snow stopped falling. What is the x-intercept
of the equation and what is its interpretation in the context of the problem?
Answer:
The x-intercept of the function is 10 which represents the number of hours until all the snow has melted
Step-by-step explanation:
There were 0 inches of snow on the lawn after 10 hours, the x intercept of 10 represents the number of hours after the storm stopped when all the snow had melted.
-2t+20=S
-2t+20=0
-2t =-20
t=10
Peony mixes red paint and white paint in the ratio 1:3 She uses four tins of red paint Work out the total number of tins of paint peony uses
Answer:
16
Step-by-step explanation:
4x3=12 tins of white paint
12+4=16 total tins
The total number of tins used by the Peony will be 16.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that Peony mixes red paint and white paint in a ratio of 1:3 She uses four tins of red paint.
The Number of red tins,
R = 4 x 1 = 4
The number of white tins,
W = 4 x 3 = 12
Total number of tins,
T = R +W
T = 4 + 12
T = 16
Therefore, the total number of tins used by the Peony will be 16.

A classroom board is 30 inches wide and 18 inches tall. Gill is putting ribbon along the outside edge of the board. How many inches of ribbon does he need?
Answer:
96 inches
Step-by-step explanation:
Use perimeter to measure the outside edges of something.
(30 × 2) + (18 × 2)
30 + 30 + 18 + 18
96 inches of the ribbon would be needed
In order to determine the inches of ribbon needed, we are to calculate the perimeter of the board
The board is in the shape of a rectangle, so we would use the formula for the perimeter of a rectangle to determine the length of the ribbon needed.
Perimeter of a rectangle = 2 x (length + breadth)
2 x (30 + 18) = 96 inches

a^2 + b^2 = c^2
ex 1.) 10^2 + 9^2 = C^2
you must find c
100 + 81 = 181
find sqrt of 181
[tex]\sqrt{181}[/tex]= 13.5
C= 13.5
Answer:
I will give two examples of the problem
Step-by-step explanation:
1. a^2+b^2=c^2
9^2+x^2=10^2
81+x^2=100
x^2=100-81
x^2=19
square root both sides and you get x=19
2.
5^2+x^2=11^2
25+x^2=121
x^2=121-25
x^2=96
square root both sides and you get 4[tex]\sqrt{6}[/tex]
There are 32 students in a class. Of the class, 3/8 of the students bring their own lunches. How many students bring their lunches?
Answer:
12 students
Step-by-step explanation:
We know that there are 32 students in a class and 3/8ths of those students bring their own lunches, so we need to find 3/8ths of 32, to find out the number of students that bring their own lunches.
Multiply 3/8 and 32
3/8 ×32
we can reduce each by 8
3×4=12
12 students.
You can double check by doing 12/32, and seeing that it is equal to 3/8

Step-by-step explanation:
Water is poured into container A so that it’s 2/3 full.
Container A is then poured into container B
Calculate the depth of the water in B
if you can’t see the picture they are the measurements:
A(H =12cm W=8cm D=8cm)
B(H=8cm W=10cm D=10cm)
Step-by-step explanation:
Volume of Container A
= (8cm)(8cm)(12cm) = 768cm³.
Volume of water = 2/3 * Volume of Container A
= (2/3) * 768cm³ = 512cm³.
Base Area of Container B
= (10cm)(10cm) = 100cm².
Hence Depth of water in Container B
= 512cm³ / 100cm² = 5.12cm.

f(x) = - 3x ^ 2 + 3x + 7 Find f(8)
Answer:
f(8) = -161
Step-by-step explanation:
Plugin 8 to each x value to get to this equation, -3(8)^2 + 3(8) + 7. Once you have done that, make sure to multiply 8 to the second power and by 3 separately to get to this equation -3(64) + 24 + 7. Combine 24 and 7 together to get 31 and multiply 64 by -3 to get -192. Add 31 now to get -161 as your answer.
Answer:
f(8)= -161
Step-by-step explanation:
fill in 8 into x, so the equation becomes
f(8)=-3(8)^2+3(8)+7
f(8)=-3(64)+24+7
f(8)=-192+31
f(8)=-161

A shipping company has 3 different sized cubed boxes. The volume of the boxes are 216in,512in,and 1000in mia needs to ship a gift with a height of 7 in what is the height in inches of the smallest box that Mia can use
Answer:
8 inches
Step-by-step explanation:
A shipping company has 3 different sized cubed boxes.
The volume of the boxes are 216in³,512in³,and 1000in³
We find the height of each volume of box.
a) 216in³,
Volume = h³
Height = cube root (216)
= 6 in
b) 512in³
= Volume = h³
Height = cube root (512)
= 8 in
c) 1000in³
Volume = h³
Height = cube root (1000)
= 10 in
Since: Mia needs to ship a gift with a height of 7 in .
Therefore: the height in inches of the smallest box that Mia can use is 8 inches (8 in)
