Question

If L-M-N, and if LM = 2x , MN = 3x - 1 , and LN = 24 , then find MN.

Answer 1

if L-M-N is what?

Answer 2

L-M-N is a line segment.

Answer 3

oh, then LM+MN=LN (in terms of the lengths)

write the equation using what you know and solve for x. then you can get LM and MN.

Answer 4

I'm not sure which equation to use, because, LM = 2x , MN = 3x - 1 , and LN = 24.

Answer 5

right... use those in the equation above.

Answer 6

you will be substituting... instead of LM use 2x. Instead of MN use 2x-1. Instead of LN use 24.

Answer 7

sorry, 3x-1 for MN.

Answer 8

My answer for MN was 14.

Answer 9

so x = 5, yeah?

Answer 10

That's what I got.

Answer 11

Awesome!!!

Answer 12

Thank you!! (:

Answer 13

you're welcome!
