Answer: 3 classes
If we removed 5 students from each of the classrooms, we would be able to keep the 18 classes and give them exactly 30 students. However, we would also have the leftover students to put into classrooms.
If there are 18 classrooms with 5 extra students from each, we can use 18*5 to find how many total students we have.
18 * 5 = 90.
If each class size is 30, we need to divide 90 by 30 to find how many classes we need.
90 / 30 = 3 classes

Answer:
x=0
Step-by-step explanation:
-3 -1
---------- = -----------
x+3 x+1
We can solve using cross products
-3 *(x+1) = -1(x+3)
-3x -3 = -1x -3
Add 3x to each side
-3x -3 +3x = -x -3 +3x
-3 = 2x -3
Add 3 to each side
-3+3 = 2x-3+3
0 =2x
Divide by 2
0/2 =2x/2
0=x
Would it be 6 because if it is third half it
Answer:
70% of the juice boxes are left.
Step-by-step explanation:
10 is the total number of juice boxes which means that 10 is 100%
If there are 10 total juice boxes and Sam drank 3, there are 7 juice boxes left. Sam drank 30% of the juice boxes which means that there is 70% of the juice boxes left.
Hope this helps!
