If y varies directly as x, and x = 48 when y = 6, find y
when x = 12.

y = 1.5

Step-by-step explanation:

Given y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 48 when y = 6

k = = =

y = x ← equation of variation

When x = 12, then

y = × 12 = 1.5
