OpenStudy (anonymous):

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

OpenStudy (anonymous):

if L-M-N is what?

OpenStudy (anonymous):

L-M-N is a line segment.

OpenStudy (anonymous):

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.

OpenStudy (anonymous):

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

OpenStudy (anonymous):

right... use those in the equation above.

OpenStudy (anonymous):

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

OpenStudy (anonymous):

sorry, 3x-1 for MN.

OpenStudy (anonymous):

My answer for MN was 14.

OpenStudy (anonymous):

so x = 5, yeah?

OpenStudy (anonymous):

That's what I got.

OpenStudy (anonymous):

Awesome!!!

OpenStudy (anonymous):

Thank you!! (:
