Economics 5 - 3 = 2
Mathematics 4
Education 3
Sociology 2
Since out of 5 sections in Economics 3 are full, there are only 2 remaining sections available for Jessica to choose from.
I think this is a combination:
n = 2 + 4 + 3 + 2 = 11
r = 1 + 1 + 1 + 1 = 4
nCr = n! / r!(n-r)! = 11! / 4!(11-4)! = 11! / 4! * 7! = 330
Jessica can have 330 different sets of classes to take.

Answer:
Alyssa's team won 20 games.
Step-by-step explanation:
We can introduce a variable that represents how many games Alyssa's team won.
Let x<em> </em>represent how many games Alyssa's team won.
We can now create a expression, we know that her team won 5 out of 7 games which would be equivalent to the fraction 5/7. We also know her team has played 28 games and five sevenths (5/7) of those they won.
This would give us the expression 5/7 = x/28.
We need to do this because 5/7 is equivalent to x the numbers of games they won over 28 the number of games they played.
Solving for 5/7 = x/28 we have:
5/7 = x/28
We need to isolate x on the right side to do so we can multiply both sides by 28.
5/7 * 28 = x/28*28 simplifying
20 = x.
Therefore the number of games Alyssa's team won is 20 games.
