Question

Given that x varies Inversely as y and when x =3 ,y =30 ,find (a) y when x = 2 and (b) x when y = 10​

Answer 1

Answer:

a. y=45,b.x=9

Step-by-step explanation:

x is inversely to y

so X=k\y

put X=3and y =30

So k= x×y

k=3*30

k=90

a. X=k/y

put the value of X and k

y=90/2

y=45

b. X= k/y

put the value of y and k

X=90/10

X=9
