$a. \: y = \frac{3}{2} x + 4 \\ \\ 1. \: \frac{3}{2} x + 4 = y \\ \\ 2. \: \frac{3}{2} x = y - 4 \\ \\ 3. \: \frac{ \frac{3}{2} x}{\frac{3}{2} } = \frac{y - 4}{2} \\ \\ x = \frac{2y - 8}{3}$

Ryans living room is 10 feet wide, 12 feet long, and 10 feet high. If one gallon of paint covers 400 square feet of surface area

Delicious77 [7]

We have to calculate the suface of the four walls and the ceiling.
Surface of the four walls=2(10 ft * 10ft ) + 2(12 ft * 10 ft)=200 ft² + 240 ft²=
=440 ft²
Surface of the ceiling=10 ft * 12 ft=120 ft²

Total surface=440 ft² + 120 ft²=560 ft²

Now, we have to caluclate the number of gallons of paint.

1 gallon------------------------400 ft²
x----------------------------------560 ft²

x=(1 gallon * 560 ft²) / 400 ft²=1.4 gallons.

answer: Ryan need to paint all four walls and the ceiling 1.4 gallons.
