Hey You!
0.90 × 8 = 7.20
Susan will need 7.2 gallons of paint to paint 8 walls.
A. 40 / 1.6 = x / 5
1.6x = 40 · 5
1.6x = 200
x = 125
b. 40 / 1.6 = 150 / x
40x = 1.6 · 150
40x = 240
x = 6
Answer:
Step-by-step explanation:
Add 18 to both sides:
Subtract 9h from both sides:
Multiply both sides by -1 and flip the symbol:

Answer:
y = 5x - 7
Step-by-step explanation:
(3 , 8) ; slope(m) = 5
Equation of the line: y - y₁ = m( x- x₁)
y - 8 = 5(x - 3)
y -8 = 5x - 5*3
y-8 = 5x - 15
y = 5x - 15 +8
y = 5x - 7
