How to solve this problem

PR = 180 cm

Step-by-step explanation:

Given PQ : QR = 7 : 3  = 7x : 3x ( x is a multiplier )

PQ - QR = 72, substitute values

7x - 3x = 72

4x = 72 ( divide both sides by 4 )

x = 18

Thus

PR = PQ + QR = 7x + 3x = 10x = 10 × 18 = 180 cm

180

Step-by-step explanation:

PQ:QR= 7:3

PQ-QR=72

PQ= 126 cm, QR= 54 cm

PR= PQ+QR= 126+54= 180 cm

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!
