Question

If 11a+11b=33 what is the average oa a and b

Answer 1

Hi ,

11a + 11b = 33

Divide each term with 11 , we get

11a/11 + 11b/11 = 33/11

a + b = 3

Multiply both sides ( 1/2 ) , we get

( a + b )/2 = 3/2

Average of a and b = ( a + b )/2 = 3/2

I hope this helps you.

Answer 2

11a +11b= 33

11(a+b) = 33

a+b = 33/11

a+b = 3

Sum of a and b =3
______________

Mean= (sum of a and b)/2

Mean = 3/2

Mean = 3/2 or 1.5

I hope this will help you
