Answer:
y = 182
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 112 when x = 8
k =
=
= 14
y = 14x ← equation of variation
When x = 13, then
y = 14 × 13 = 182
first most important effect is the erosion and the second most important effect is weathering.
