Answer:
20
Step-by-step explanation:
x^2/y
Let x=10 and y=5
10^2/5
100/5
20
1.

<u />⇔

⇔

R: She can buy
8 crackers
2. Amy used 13%
Dan used 0,14*100 = 14%
Mike used 0,5*100 = 50%
R: Mike used the greatest amount of milk.
Given, y varies directly as x
So,

Where c is a constant
When y equals 5 when x is 8
So,

So, the relation between y and x

now , when x = 9
Substitute with x to find y

So, the answer is option 2. y = 45/8
X by itself is 1, otherwise it is the number to the left
The symmetric property of equality.
This property states that: if a = b, b = a.
