Question

If y=6 when x=24 what is the value of x when y=7

Answer 1

Answer: The required value of x is 28.

Step-by-step explanation: Given that y = 6 when x = 24.

We are to find the value of x when y = 7.

Since x and y are directly related, so we have

`x\propto y\\\\\Rightarrow x=ky~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[\textup{where k is the constant of proportionality}].`

When y = 6 and x = 24, we get

`24=k*6\\\\\Rightarrow k=(24)/(6)\\\\\Rightarrow k=4.`

Therefore, when y = 7, we get

`x=7*4=28.`

Thus, the required value of x is 28.
