Question

X varies inversely as Y when x=15 then y=10,if x=20 then y=? (ans it quick plz I need it know)​

Answer 1

Answer:

It is x56

Step-by-step explanation:

Answer 2

We know that,

In inverse proportions,

x1y1 = x2y2

So when x1= 15 and y1 = 10 and x2= 20 and y2= ?

15 * 10 = 20 * y2

y2 = 150/20

    = 7.5

Thus when x = 20 , y = 7.5

Hope it helps !
