w + x + y = 21
Average of xy vs 7
To determine the average of x and y, we would need to know their sum. From the information given in the prompt, we know that:
x + y + w = 21x + y = 21 – w
This means that the average of x and y is:
However, we have no idea what the value of w is, so the average of x and y could be less than, equal to, or greater than 7. For example:
w = 1
10Column A's 10 > Column B's 7
w = 11
5Column A's 5 < Column B's 7
Therefore, the relationship cannot be determined.
