Answer:
17 students per teacher, 9 students per tutor. You need 10 tutors if the school had 90 students.
Step-by-step explanation:
51 students divided by 3 teachers = 17 students per teacher.
45 students divided by 5 tutors = 9 students per teacher.
If there are 9 students per tutor 9 * 10 = 90 so ten tutors
Answer:
the coefficient of x is 2
Step-by-step explanation:
(3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - (3x - y - z)
Apply the distributive law: - (a - b) = -a + b
Therefore, - (3x - y - z) = -3x + y + z
So (3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - 3x + y + z
Collect like terms: = 3x + 2x - 3x - y - y + y + z - z + z
Combine like terms: = 2x - y + z
Therefore, the coefficient of x is 2
Therefore, the coefficient of x is 2
The customer’s current balance after an overpayment last month is D. $174.80.
<h3>How to illustrate the information?</h3>
It should be noted that after an overpayment last month, the balance on a customer’s billing statement is −$50.00 and this month’s new charges are $124.80.
Therefore, the customer’s current balance will be:
= $124.80 - (-$50)
= $124.80 + $50
= $174.80
