90x+60y=72
60y=-90x+72
y=-1.5x+1.2
then create a graph using this formula.
Hope this helps!
I would prefer to solve this in a decimal form
I will show this to u in 2 ways
1:.75::X:2.25
(1*2.25)/.75x
2.25/.75x
X=3
2.25/.75=3
when we divide the number of hours played by hors for one game we get the number of games that could be played
Answer:
-7
Step-by-step explanation:
You should be able to multiply 91 by 8 to get the sum of the first 8 tests, then add the score on the 9th test. Then to get the average of the sum of the 9 tests you need to divide it by 9.
((91*8)+78)/9=89.555555555555.... So, 90%
