The value of y when x = 5.25 is 210.
Given that the value of y varies directly with x.
When y = 30, x = 0.75.
We need to find the value of y when x = 5.25,
If the value of y varies directly with x, it means that the relationship between y and x can be expressed as:
y = kx
Where "k" is the constant of proportionality. To find the value of "k," we can use the given information:
When y = 30, x = 0.75:
30 = k × 0.75
Now, solve for "k":
k = 30 / 0.75
k = 40
Now that we have the value of "k," we can use it to find the value of y when x = 5.25:
y = k x
y = 40 × 5.25
y = 210
So, when x = 5.25, the value of y is 210.
