Answer:
C. x = 4 is the correct answer
Step-by-step 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
