If 23m − n = p, then which of the following represents the average (arithmetic mean) of m, n, and p, in terms of m?
Answer/Solution
8m
Steps/Work
23m - n = p
Add n to both sides:
23m = n + p
Add m to both sides:
24m = n + p + m
Now, divide both sides by 3
8m = (n + p + m)/3 = the average of n, p, and m
E
Add n to both sides:
23m = n + p
Add m to both sides:
24m = n + p + m
Now, divide both sides by 3
8m = (n + p + m)/3 = the average of n, p, and m
E
