Q:
# For what value of x will 9, 16 and x have the same mean (average) as that of 26 and 12?

Accepted Solution

A:

Lets set up the equation for this problem: (9+16+x)/3 = (26+12)/2

Simplify: (9+16+x)/3 = 38/2

(9+16+x)/3 = 19

(9+16+x) = 19x3

9+16+x = 57

25 + x = 57

x = 57- 25

x= 32

Hope this helps!
