Question

Point V lies between points U and W on Line segment U W.
If UW = 9x – 9, what is UW in units?

Answer 1

36

Explanation:

UW = UV + VW

9x - 9 = 2x - 4 + 4x + 10

9x - 2x - 4x = -4 + 10 + 9

3x = 15

x = 5

UW = 9x - 9 = 9(5) - 9 = 45 - 9 = 36

Answer 2

See Below

Explanation:

2x - 4 + 4x + 10 = 9x - 9

6x + 6 = 9x - 9

3x = 15

x = 5

UW = 9x-9 = 9*5-9

UW = 36 units
