If KL= 4x, LM=5x , and KM=9, what is KL

Question

simplify your answer and write it as a proper fraction, mixed number, of integer

Answer 1

Hi. If you look carefully, KL + LM = KM. You can draw them on a number line, with lengths given, for clarification.

You will see that 4x + 5x = 9. Therefore, 9x = 9, and x = 1. As a result, KL = 4(1) = 4.
