Question

Solve for x. Show all work.

Answer 1

Answer:

x = 10.

Step-by-step explanation:

By similar triangles:

3x - 5 / (3x - 5 +10) = 20 / 28

3x-5 / 3x+5 = 5/7

7(3x - 5) = 5(3x + 5)

21x - 35 = 15x + 25

6x = 60

x = 10.

Answer 2

Answer:

x= 10

Step-by-step explanation:

By similar triangles:

3x - 5 / (3x - 5 +10) = 20 / 28

3x-5 / 3x+5 = 5/7
