If the sum of 3, 7 and x is 18, then the average (arithmetic mean) of 3, 7, and x is ______?
- 10
- 8
- 6
- None of these
Explanation
Given that the sum of 3, 7, and x is 18:
3 + 7 + x = 18
Combine constants:
10 + x = 18
Subtract 10 from both sides:
x = 8
Now, find the average (arithmetic mean) of 3, 7, and x:
Average = (3 + 7 + x) / 3
= (3 + 7 + 8) / 3
= 18 / 3
= 6
