Question

If G is the midpoint of CD, and CG= 5x-1 and GD=7x-13. What is the value of CD?

Answer 1

Explanation:

CD = CG + GD

but CG = GD since both sides are the same (G is midpoint)

so,

5x - 1 = 7x - 13

2x = 12

x = 6

CD = 5x - 1 + 7x - 13

CD = 12x - 14

CD = (12 * 6) - 14

CD = 72 - 14

CD = 58
