7 , it’s x = 12 1/3, or in decimal form, 12.33. And at 8, it’s x = -6/11, or in decimal form, -0.54
7) y = 4x
8) y = 7x/8
9) y = 25x/3
I think this are the answers.
Hi!
We will solve this using ratios, like this:
4 1/2 = 4,5 kg of olive oil for 27 $
1 kg of olive oil for x $
_____________________________
x = (27*1)/4,5
x = 27/4,5
x = 6 $ per kilogram
Hope this helps!
Answer: The total number of student in the school = 240.
Step-by-step explanation:
Let x be the total number of students in the school.
Given: 35% of the students at Charles drew middle school are 6th graders.
i.e. Number of sixth graders = 35% of x = 0.35x [35% = 0.35]
Since there are 84 sixth graders in the school,
So 
Divide both sides by 0.35, we get

Hence, the total number of student in the school = 240.
X > -4 is the answer if you solve for x.
