Answer:
The answer is: 5.
Step-by-step explanation:
Set up an equation:
2 / 7 = y / 17.5
Cross multiply:
7y = 2 * 17.5
7y = 35
y = 35 / 7 = 5
Answer:
y = 5.
Step-by-step explanation:
Direct proportionality is : y = kx where k is a constant.
Finding k by substituting the given values of x and y:
2 = k * 7
k = 2/7.
So the equation is y = 2/7 x.
When x = 17.5:
y = 2/7 * 17.5
y = 5.
