Answer:
25
Step-by-step explanation:
you divide each term by 2
Answer:
26
Step-by-step explanation:
You want to know the value of x that makes y=1000. You can plug the equation in to your calculator or desmos. Look at the table for when y=1000. X is 26.
To check, plug in 26 for x. 26^2 + 20(26) - 196 = 1000.
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.
