Question

Joelle set up the following proportion to solve for x. determine if her proportion is correct. if not, explain what is wrong with it.

Answer 1

Its B just took the quiz

Answer 2

The proportion Joelle set up is (4/6) = (5/X). The proportion is incorrect, because the side BD (which is equal to 4) is proportional to the side BA (equal to 9), not simply side DA (equal to 5, which Joelle had used). The correct proportion is (4/6) = (9/X), where X = 13.5.
