The expression that can be used to find the value of y when x is 112 is
y= 3.6*112
Step-by-step explanation:
We are given that y varies directly with x, and y=18 when x = 5.
We need to find the expression used to find the value of y when x = 112
When y varies with x, it means:
y ∝ x
y= k x
where k is constant of proportionality.
if y= 18 and x = 5, then finding k:
y = k x
18= k*5
k= 18/5
k= 3.6
So, value of k is: 3.6
Finding expression for y when x = 112
y= k x
k= 3.6 and y = 112
y= 3.6*112
So, the expression that can be used to find the value of y when x is 112 is
y= 3.6*112
