Suppose that y varies directly with x and y=5 when x=6. What is y when x=5? Be sure to simplify your answer.
Charra [1.4K]

Answer:

y = \frac{25}{6}

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 5 when x = 6

k = \frac{y}{x} = \frac{5}{6}

y = \frac{5}{6} x ← equation of variation

When x = 5, then

y = \frac{5}{6} × 5 = \frac{25}{6}
