Much better than just fishing for answers on some boring website.
2n + 10= -2
-10 -10
2n= -12
/2 /2
n= -6
To the find average of the test scores, we need to find the mean.
To find the mean, all we need to do is add up all the numbers and then divide the answer by how many numbers there are
81 + 83 + 85 = 249
249 ÷ 3 = 83
Therefore, the new average is 83
Hope this helps
Y=-7x-5
9=-7(-2)-5
9=14-5
9=9
