Question

The variable x varies directly as y When y is 10.x is 3. Find y when x is 9
guys pls solve my question ​

Answer 1

Answer:

Since x varies directly as y

So, y = k x ,where k is a constant.

when, x=3/2 ,y=10

10=k*3/2

k=20/3

now comes the question.

given x=9 and we know that k=20/3

So, y=(20/3)*9

y=60.

I Hope it helps.
