The answer would be wx(yz) because the associative property says that you can change where the parenthesis are while keeping the same equation.
The equation is w(xy)z, but moving the parenthesis some where else will not change it, such as wx(yz).
You first find the average of the first two test scores. When you find the average, you add the two numbers together and then divide by two which gives you 89. You then plug in different scores above the number 89 and find the average of those (89 and x) to see which gives you an average of 92. It’s mostly a guess and check type of problem.

hope it's helps .
-7x+12-2x=23+13x
First take away 13x from the right side and put it on the left side adding taking it away from -7x
-7x(-13x)=-20x
-20x+12-2x=23
then add 2x to -20x
and move 12 to the other side, minus it off of 23
-18x=11
then divide -18x on both sides
then x=-11/18
first you put 18/y=2
you multiply by 18 to get y=36
your answer is 36, y=36
