Question

For what value of x will 55 and x have the mean (average) as 67? explain how you got your answer

Answer 1

X=79

Explanation:

The answer can be found by finding the difference of 67 and 55 which would be 12, then adding 12 and 67 to get 79. I can do this because if 2 numbers are split equally between them, then adding an number to get one will get you the other. It may seem confusing, comment if you still need help.
