21) Tracy wants an average grade of 88 from her four geometry exams. The scores for her first
three exams are 85,98, and 81. What grade
would Tracy need to earn on her fourth exam to
have an average grade of 88?

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
