We will use the segment addition postulate.

PQ + QR = PR

4x - 1 + 3x - 1 = 54

7x - 2 = 54

7x = 56

x = 8

So QR is 3(8) - 1 or 24 - 1 which is 23.

Answer:

QR is 23

Step-by-step explanation:

PR = 54
Which means:
(4x-1)+(3x-1)=54
We can solve for x to find what QR is:
7x-2 =54
7x=56
x=8
Plug in x for QR equation:
3(8)-1 = 24-1=23
23 is the answer
