Answer:
25 students peer teacher, 22 students per tutor, 4 tutors for 81 students
Step-by-step explanation:
You need to find the unit rate,
for the teachers, to find the unit rate would be 125 divided by 5. For tutors it would be 88 divided by 4.
Then to find how many tutors you need for 81 students you would need 4 tutors because you want to divide 81 by the unit rate we got (22), and since the answer would be a decimal (3.68.....) you would need to round the whole number up to four because you cant have a decimal of a person.
Divide by 5, answer is 1/7
A) h=hours
b) 40 (h)+30= amount earned
hope that is right
Answer:
1. 62
2. 13
3. 6
4. 18
5. 3
Step-by-step explanation:
1. Let's use pemdas
16*1/2= 8
32 / 4 * 8 - 2
8*8 - 2
64 - 2
= 62
2. Let's use pemdas
5*2/5 = 2
20 / 2 + 3
10 +3
= 13
3. Let's use pemdas
1/2 * 24 / 3 +2
12 / 3 +2
4 +2
=6
4. Let's use pemdas
2 * (6 / 2 + 8) -4
2 * 11 - 4
22 - 4
= 18
5. Let's use pemdas
(28 / 7 +6 / 3) * 1/2
( 4 + 2) *1/2
6 *1/2
= 3
