Step-by-step explanation:
Given
Represent Fred with F; Norman with N and Dave with D.
Required
Determine the arithmetic mean of F and N
First, we have that:
Substitute 44 for D
Subtract 44 from both sides
Arithmetic mean of F and N is calculated as follows:
Answer: 72.5 ounces per day
1)
2)
Since A is the midpoint of BC, we can assume BA and AC are equal to each other.
We also know that BC = BA + AC = 23 + 23 = 46
