Suppose M is between L and N. Use the Postulate to....

[perky_jennie]

In my geometry class, we are reviewing some stuff and i have no clue how to do this so anyone who can help me it would be very appreciated ok here is the problem..

Suppose M is between L and N. Use the Segment Addition Postulate to solve for the variables. Then find the lengths of LM(has a line over it) and MN and LN( they all have lines over them.)

LM= 7y+9
MN= 3y+4
LN= 143

Re: help me plezzz !!!! anyone !!!

i have no clue

I REALLY hate that. :evil: Are you in the right class? You MUST have SOME clue. :roll: Change your thinking first. Only then will there be any hope.


L-------M-------N

LM = 7y+9
MN = 3y+4
LN = 143 = LM + MN = 7t+9 + 3y+4 = 10y + 13

Are we getting anywhere?
