You know that Allie takes 8 hours to paint a fence by herself, but if Bert helps her, it only takes them 6 hours working together. One day, Allie is out sick. How many hours will it take Bert to paint the fence alone?

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
