Answer:

C. x = 4 is the correct answer

Explanation:

To solve this, we will create a proportion.

The proportion will show the ratio of ABC to EDC and allow us to solve for x.

20 - x / 20 = x / 5

100 - 5x = 20x

100 - 5x + 5x = 20x + 5x

100 = 25x

100 / 25 = 25x / 25

4 = x

C. x = 4 is the correct answer
