Answer:

y = [tex]\frac{25}{6}[/tex]

Step-by-step explanation:

Given that 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 = [tex]\frac{y}{x}[/tex] = [tex]\frac{5}{6}[/tex], thus

y = [tex]\frac{5}{6}[/tex] x ← equation of variation

When x = 5, then

y = [tex]\frac{5}{6}[/tex] × 5 = [tex]\frac{25}{6}[/tex]
