An unknown number w is 30 more than an unknown number p. The number w is also p less than 5
AleksandrR [38]
The problem statement gives rise to two equations.
  w = 30 + p . . . . . w is 30 more than p
  w = 5 - p . . . . . .. w is p less than 5

Add these two equations to get
  2w = 35
  w = 35/2 = 17.5
  p = 5 - w = -12.5

The unknown number w is 17.5.
The unknown number p is -12.5.

Angle pwm is equal to angle pkm
Len [333]
<h3>Answer: 24 (choice C)</h3>

Assuming M is a midpoint of KW, this means that WM and KM are congruent

WM = KM

x+3 = 2(x-3) ... substitution

x+3 = 2x-6

2x-6 = x+3

2x-6-x = x+3-x .... subtract x from both sides

x-6 = 3

x-6+6 = 3+6 ... add 6 to both sides

x = 9

Use x = 9 to find the length of WM

WM = x+3 = 9+3 = 12

Which can be used to find the length of KM as well

KM = 2(x-3) = 2(9-3) = 2(6) = 12

both lengths are the same (12) as expected

This makes WK to be

WK = WM + KM

WK = 12 + 12

WK = 24
