Answer:

<h2>QS = 42</h2><h2></h2>

Step-by-step explanation:

R is midpoint

|<---------------- QS -------------------->|

Q---------------------R--------------------S

       8x - 51                 3x - 6

find: QS

QR = RS

8x - 51 = 3x - 6

8x - 3x = 51 - 6

5x = 45

x = 45/5

x = 9

QS = QR + RS

QS = (8x - 51) + (3x - 6)

plugin the value of x=9 into the equation above:

QS = (8(9) - 51) + (3(9) - 6)

QS = 72 - 51 + 27 - 6

QS = 42
