A+b=100
a-b=6 ⇒ a= b+6
(b+6)+b=100
2b+6=100
2b=100-6
2b=94
b=94:2
b=47
a=47+6
a=53

Answer:
27
Step-by-step explanation:
Hi there!
We are given this set of data:
22, 15, 31, 40, 27
And we want to find the average (or the mean) of the set
To find the mean, we add up all of the values of the data set and then divide it by how many pieces of data we have
So first, add 22, 15, 31, 40 and 27 together
22+15+31+40+27=135
We have 5 pieces of data, so divide 135 by 5
135/5=27
The mean is 27
Hope this helps!
