A quantity, y, varies directly as x. When y= 10. x= 6. Find x when y= 14.
4.3
23.3
60

x = 8.4

Step-by-step explanation:

The function can be written as

y = kx

Where

k = constant of proportionality

When y= 10. x= 6

y = kx

Substitute into the equation

10 = k * 6

10 = 6 k

Divide both sides by 6

k = 10 / 6

k = 5 / 3

Or

k = 1.67

Find x when y= 14

y = k * x

14 = 5/3x

x = 14 ÷ 5/3

= 14 × 3/5

= 42 / 5

= 8.4

x = 8.4

8.4
