Question

What is the value of x? What is the value of y?

Answer 1

Answer:

The answer to your question is x = 30; y = 14

Step-by-step explanation:

Data

JK = x            PR = 20

JL = 21           PQ = y

LK = 18           QR = 12

Process

1.- Find x

Use proportions to find it

                 JK/PR = LK/QR

Substitution

                 x/20 = 18/12

Solve for x

                  x = 20(18/12)

                  x = 360/12

                 x = 30

2.- Find y

                PQ/JL = PR/JK

Substitution

                y/21 = 20/30

Solve for y

                y = 21(20/30)

                y = 420/30

                y = 14
