Question

If PR=40, what are PQ and QR?

Answer 1

B

Explanation:

I did it in my head but pretty much just add the 5x-2 and x+ 12 then set it equal to 40. u get x = 5. plug x back in and you get 23 and 17

Answer 2

The answer is B

Explanation:

5x - 2 + x + 12 = 40

6x + 10 = 40

6x = 30

x = 5

5(5) - 2

25 - 2

PQ = 23

(5) + 12

QR = 17
