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
<span>-n -21= - 4x
</span>-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

Find m∠U.<br> Write your answer as an integer or as a decimal rounded to the nearest tenth.
Ilia_Sergeevich [38]

Answer:

∠U = 56.4

Step-by-step explanation:

We can use trigonometric functions to solve this

Here we are given the opposite side of ∠U as well as the adjacent side.

When dealing with the adjacent and opposite side we use sin

Sin = Opposite side / Adjacent side

Opp = 5 and adj = 6

So

Sin(U) = 5/6

* take the inverse sine of both sides *

arc(sin)(u) = u

arcsin(5/6) = 56.4 *( rounded to the nearest tenth )

∠U = 56.4
