Question

The value of y varies directly with x. If x = 16 when y = 20, find the value of y when x = 60?​

Answer 1

y = 75 when x = 60

Explanation:

To solve this, we will use a proportion, since x and y vary directly with each other.

16 / 20 = 60 / y

Step 1: Cross-Multiply

16y = 1200

Step 2: Divide both sides by 16

16y / 16 = 1200 / 16

y = 75

Step 3: Check

16 / 20 = 60 / 75

1200 = 1200 ✅

y = 75 when x = 60
