Given That a is the average of 3 and 6, compare?

Question

A. 3a

B. a + 6

I pick A, is it the right answer??

Answer 1

If you are looking for the highest value then yes.

Answer 2

No, not unless you missed out part of the question.  The average (mean) of 3 and 6 is (3+6)/2 = 4.5

A. 3a = 3(4.5) = 13.5

B. a + 6 = 4.5 + 6 = 10.5

So, comparing A and B, A is greater than B.

Answer 3

a= 4.5

A. 13.5

B. 10.5

A is greater
