Question

XY has a length of 20 and contains a point Z in between. If XZ = -5x+1 and ZY = 3x+5, find ZY.

​

Answer 1

10.25 or 10 and 1/4

Explanation:

Answer 2

10.25

Explanation:

Assuming that XZ = 5x + 1 (not -5x + 1)

XY = XZ + ZY

20 = 5x + 1 + 3x + 5

20 = 8x + 6

14 = 8x

8x = 14

x = 14/8 = 1.75

ZY = 3x + 5

ZY = 3 * 1.75 + 5

ZY = 5.25 + 5

ZY = 10.25
