Answer: 1.333333333333333333334
Pretty sure it would be 22.
17+7^2=66
17-2(7)=3 and you would divide 66 by 3
The college student took 13 courses of 3 credit hours.
Step-by-step explanation:
Given,
Total credits = 59
Total courses = 18
Let,
Number of 3 credit hour courses = x
Number of 4 credit hour courses = y
According to given statement;
x+y=18 Eqn 1
3x+4y=59 Eqn 2
We will eliminate y to find the number of 3 credit hour courses, therefore,
Multiplying Eqn 1 by 4

Subtracting Eqn 2 from Eqn 3

The college student took 13 courses of 3 credit hours.
