Answer:

−3(−3x−7)=48

Divide both sides by −3.

−3x−7=   48

​ Divide 48 by −3 to get −16.

−3x−7=−16

Add 7 to both sides.

−3x=−16+7

Add −16 and 7 to get −9.

−3x=−9

Divide both sides by −3.

x=  −3 −9

​ Divide −9 by −3 to get 3.

x=3

<u>Answer:</u>

  • x = 3

<u>Step-by-step explanation:</u>

  • -3(-3x - 7) = 48
  • => 9x + 21 = 48
  • => 9x = 48 - 21
  • => 9x = 27
  • => x = 3

<u>Conclusion: </u>

Therefore, the answer is 'x = 3'.

Find the surface area of this cube. Be sure to include the correct unit in your answer.
NikAS [45]
Are the dimensions 8yd x 8yd x 8yd? If so this is how you do:

First calculate the area or one side. Then multiply it by 6 as all the sides of the cube have the same area.

Side area = 8yd x 8yd = 64yd^2

Surface area = 6 x 64yd^2 = 384yd^2

Write the slope intercept form of the equation of the line through the given points and slope 1,1 and slope of -3/5
Maslowich

Slope is already given in the question so we only need to solve for the y-intercept.

Slope intercept form: y = mx + b

m = slope

b = y-intercept

-3/5 = -0.6

1 = -0.6(1) + b

1 = -0.6 + b

1 + 0.6 = -0.6 + b + 0.6

1.6 = b

Now, write in slope-intercept form.

y = -3/5x - 1.6
