Question

The average of 2 numbers is 17. One of those numbers were 22, what was the other number?

Answer 1

To find average of two numbers, call numbers a and b\[\frac{ a+b }{ 2 }=average\]

Answer 2

yes i know that. That does not answer my question though

Answer 3

\[\frac{ x+22 }{ 2 } = 17\]
Multiply both sides by 2

x+22 = 34
-22 -22

x=12

Answer 4

Thanks!
