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 :-
[tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]
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
[tex]\dfrac{3}{6}=\dfrac{8}{y}\\\\\Rightarrow\ y=\dfrac{8\times6}{3}\\\\\Rightarrow\ y=16[/tex]
Hence, the value of y = 16 , when x=8.
