Question

If y is directly proportional to x and y=12 when x=4, then find the value of y when x= 10
i) 10
ii) 20
iii) 30
iv) 35

Answer 1

Answer:

okk its preety simple ,

direct proportional means that if we increase x by one number then y should also be inscresed by same number okk

As per you question,

when x=4 so y=12

Now if we increase x by 6 so y should be 20 okkkk

Answer 2

Answer:

30

Step-by-step explanation:

The answer is 30.

The value of y=12

The value of x=4

y is directly proportional to x.

Directly proportional means that if a product is increased than the other product will also increase.

Here;

y is directly proportional to x

y=kx (after taking constant)

12/4=k

k=3

Now when x=10;

y=kx

y=(3)(10)

y=30

The value of y is 30 when the value of x is 10.
