Question

The value of y varies directly with x. When y = 85, x = 14. What is the value of y when x is 112?

Answer 1

Answer:

y = 679.952

Step-by-step explanation:

It is given that, the value of y varies directly with x.

y₁ = 85, x₁ = 14

$y\propto x\\\\y=kx\\\\k=\dfrac{y}{x}\\\\k=\dfrac{85}{14}\\\\k=6.071$

We need to find the value of y when x is 112.

$y=k\times x\\\\=6.071\times 112\\\\y=679.952$

So, the value of y is 679.952 when x is 112.
