4. 
Points P, Q, R, S, and T are collinear. If PT = 6PQ, QT = 20, and PQ = QR = RS, find ST.


5. 
Suppose M is between L and N. LM = (2 1/3y + 4), MN = (2y + 7/2), LN = 58. Find the value of y. 

6. 
Points M, N, and X are collinear and X is between M and N. If MN = 20 and the ratio between MX and NX is 2:3, find the length of _{}. 

7. 
Point Q is between points P and R on _{}. If PR = 87, PQ = 5x  259 and RQ = 3x  102, find the value of x. 

8. 
_{} and _{} bisect each other at point E. If AE = 5x + 3y  56, BE = 3x + 18y  194, CE = 7x + 20y  332, and DE = x  13y + 184, what are the values of x and y?
