If x and y vary inversely and y = 45. Find x when constant of variation​

Answer 1

Answer:

The value of y=5 when x=15.

Step-by-step explanation:

Given : If x and y vary inversely and x= 25, when y= 3.

To Find : The value of y, when x=15?

Solution :

As x and y vary inversely proportional which means

Where, k is inversely proportional constant

So,  

Now, Substituting x=25 and y=3

Put back in the equation,

Now, Put x=15

Therefore, The value of y=5 when x=15.
