Question

x and y vary directly and x= 19/2. Find y, when the constant of variation =1/2​

Answer 1

Step-by-step explanation:

x/y=k

19/2/y=1/2

19/2=1/2y

19/2×2\1=y

y=19

Answer 2

The value of y is 19.

Step-by-step explanation:

x and y vary directly.

x = ky...............(i)

Where k = constant of variation

Given, x = $\frac{19}{2}$ and k = $\frac{1}{2}$

Plug the values in equation(i),

=> $\frac{19}{2} = \frac{1}{2}\times y$

=> y = 19

Hence, the value of y is 19.
