The first step to solve this problem, you have to compute
first for the total number of students:
6 math classes x 27 students per class = 162 students
Now, you know that there are 162 students all in all in the
school. The next step is to compute for the total cost of both the book and the
calculator per student.
$45.10 (Book) + $57.80 (Calculator) = $102.90 (total cost
per student)
To compute for the total cost that the school will pay, you
have to multiply the total cost per student to the number of students in
school.
$102.90 per student x 162 students = $16,669.80
Therefore, the total cost the school will pay is $16,669.80.
f(x) = 3/(x + 2) - √x - 3
f(7) = 3/(7 + 2) - √7 - 3
f(7) = 3/9 - √4
f(7) = 0.333 - 2
f(7) = -1.67
I think it would look like this 20:28 or 120:150
I don't understand the question. Can I have some context?
The first step, would be to make the percent a fraction. 15%=15/100.
So, if they played 60 games, and you want to find how many they lost, you would write x/60, when x=games lost.
15 x
___=___
100 60
Simplify the fraction on the left. Divide the numerator (top) and the denominator (bottom) by 5, leaving you with 3/20.
3/20=x/60
Make the denominators (bottom) similar
9/60=x/60
x=9
