Question

ti is given that y varies directly with 2x+6 and x =3 when y=12 . find the value of x when y =30

Answer 1

Heya ☺

Given that

x = 3 when y = 12

We have to find the value of x when y = 30

It is a case of direct variation

3/12 = x/30

=> 3x = 12 × 30

=> x = 12 × 30/3

=> x = 120




Thanks

Answer 2

Answer:

The value of x =1 20

Step-by-step explanation:

In the given question,

It is given that

if x = 3, the value of y = 12

Now, we need to find the value of x if y = 30

According to the question, the y varies directly with

This implies that , the direct relation is

3/12 = x/30

3x = 12 × 30

or x = 12 × 30/3

or x = 120
