Lets x to be number of students.

1) If each students get 3 ml, then all students get 3x ml.
There was n ml.
(n-3x) ml leftover

n - 3x = 5

2) If each students get 4 ml.
then all students get 4x ml.

n+21 = 4x

3)
n - 3x = 5
- (n+21 = 4x) -------> -n -21=-4x

n - 3x = 5
-n -21= - 4x
-3x-21=5 - 4x
x=5+21
x=26

Answer : 26 students

Check:
x=26, n-3x = 5, n-3*26=5, n=83
n+21 = 4x
83+21=4*26

(time limit!) what is the volume below? A) 112 B) 224 C) 784 D) 896

Radda [10]

To find a volume of a cylinder we use the following formula:
$v = \pi {r}^{2} h$
Plug in the values:

$v = \pi \times {8}^{2} \times 14$
Take the square:
$v = \pi \times 64 \times 14$
Multiply the numbers:
$v =896 \pi {m}^{2}$
