<PRE><B>Question 209468</B>
Suppose M is Between L and N. Use the Segment Addition Postulate to solve for the variable. Then find the lengths of LM MN and LN
 
LM= 3x+5
 
MN = 2x-5
 
LN = 23
 
---------------------
Equation:
3x+5 + 2x-5 = 23
5x = 23
x = (23/5)
------------------------
LM = 3x+5 = 3(23/5)+5 = (69/5)+(25/5) = 94/5 = 18 4/5
-----------------------
MN = 2x-5 = 2(23/5)-5 = (46/5)-(25/5) = 21/5 = 4 1/5
