For this case, the first thing we must do is define variables:
x: students of group 1
y: students of group 2
We now write the system of equations that models the problem:

Solving the system by substitution we have:



Then, the value of y is given by:

Answer:
8 students of group 1
20 students of group 2
The answer is two. This is because to find the volume of the figure, you need to multiple the length, width, and height of the figure. After doing so, you get 462. When you divide this by 231, you get 2.
To find the probability of pulling something first take note of the total number and the amount of which you want to select.
100 and 10
Now set them up as a fraction
10/100 and simplify
1/10 or 10%
2.53, 2.5 , 2.35, 2.30, 2.05, 2.03
