Answer: x = 4
Step-by-step explanation:
From the question, we were told that x varies directly as y. This means that: x = ay
where the constant is a.
Then, we solve for a
x = ay
Divide both side by y
a = x/y
When x = 2.5 when y = 10, a will be:
a = x/y
a = 2.5/10
= 0.25
To find x when y= 16
Recall that x = ay
x = 0.25 × 16
x = 4
