Question

x varies inversely as y and y= 60, when x= 1.5. find x, when y=4.5

Answer 1

Hey



It is given that


x inversely proportional to y


So ,


When y = 60


then x = 1.5


60 = 1 / 1.5

When y = 1 , then


1 = 1 / 9

When y = 4.5 , then


4.5 = 4.5 / 9


= 1/ 2

= 0.5


so , x = 0.5


thanks :)

Answer 2

so firstly we divide y by x
we get 40...
so it means x is 40 times the y (1)

divide the val. of eq 1 in another value y ..i.e y= 4.5
so we get x= 4.5 / 40
x = 0.11


We check the answer ....
for check
we know that x is 40 times the y
so value of x 0.11 multiply by 40
so we get y =4.5
