Answer:

(x+1,1x)2=average

Step-by-step explanation:

We know the second test is ten porcent higher than the firt and we can represent the second as an expression of the first

Lets say 1 represent 100% and thats the porcent in the first test

Then 1,1 represent 110% and thats second test in terms of the first test

The average is (test1+test2)2=average

Test1=x

Test2=110%x=1,1x

The expression is

(x+1,1x)/2=average
