Answer:

m = -7

Step-by-step explanation:

  1. Combine like factors. It should now look like this: 6m - 9m = 6 + 15
  2. 6 + 15 = 21
  3. Plug 21 in: 6m - 9m = 21
  4. 6m - 9m = -3m
  5. Plug -3m in: -3m = 21
  6. Divide each side by -3 to cancel out the -3 next to x. It should now look like this: m = -7

I hope this helps!

Answer:

m=-7

Step-by-step explanation:

6m-6=9m+15

Add 6 to both sides:

6m-6+6=9m+15+6

6m=9m+21

Subtract 9m from both sides:

6m-9m=9m+21-9m

-3m=21

Divide both sides by -3:

\frac{-3m}{-3}=\frac{21}{-3}

m=-7

Time to paint the living room. The room measures 20 feet wide by 30 feet long by 12
chubhunter [2.5K]

The cost to paint the walls and the ceiling is $855

<h3></h3><h3>How much will it cost?</h3>

First, we need to find the area that will be painted.

The area of two of the walls is:

A = 20ft*12ft = 240ft²

The area of the other two walls:

A' = 30ft*12ft = 360ft²

The area of the ceiling is:

A'' = 20ft*30ft = 600ft²

We also need to subtract the areas of the two doors and the 4 windows.

Each door is 7ft by 3ft, so the area of each door is:

a = 7ft*3ft = 21ft²

Each window is 4ft by 3ft:

a' = 4ft*3ft = 12ft²

Then the total area that will be painted is:

area = 2A + 2A' + A - 2a - 4a'

area = 2*( 240ft²) + 2*(360ft²) + 600ft² - 2*(21ft²) - 4*(12ft²)

area = 1,710 ft²

We know that we need two coats of paint to cover that area, and the cost per square foot of paint is $0.25, then the total cost is:

C = $0.25*2*(1,710) = $855

The cost to paint the walls and the ceiling is $855
