Question

For the inverse variation equation xy = k, what is the value of x when y = 4 and k = 7? 3 28

Answer 1

It would be 7/4 or 1.75 if needed to be in decimal format.

Answer 2

Answer:

The value of x is $\frac{7}{4}$.

Step-by-step explanation:

It is given that the inverse variation equation is

$xy=k$                  ..... (1)

The value of y is 4 and the value of k is 7.

Substitute y=4 and k=7 in equation (1).

$x\times 4=7$

Divide both sides by 4.

$\frac{x\times 4}{4}=\frac{7}{4}$

$x=\frac{7}{4}$

Therefore the value of x is $\frac{7}{4}$.
