Question

If x and y vary inversely and x = 25, y =3. Find y, when x= 15.

Answer 1

Answer:

y=5

Step-by-step explanation:

x=25

y=3

y=3x=15

y=3x=15y=?

y=3x=15y=?let y be a,

y=3x=15y=?let y be a,so,

y=3x=15y=?let y be a,so,25/15 = a/3

y=3x=15y=?let y be a,so,25/15 = a/3 25*3/15 = a

a= 5

therefore, y=5
