Answer: 16

Step-by-step explanation:

We know that when rwo quantities x and y are directly proportional , then the equation shows the direct proportional relationship between then is given by :-

\(\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}\)

Given: If y is 6 when x is 3 and y varies directly with x.

To find : y when x is 8

Substituting the given values in the equation , we get

\(\dfrac{3}{6}=\dfrac{8}{y}\\\\\Rightarrow\ y=\dfrac{8\times6}{3}\\\\\Rightarrow\ y=16\)

Hence, the value of y = 16 , when x=8.
