Answer:
7 days
Step-by-step explanation:
So! Ms. Masi earns $11.25 everyday, and is paying her brother back everyday. Let's make an equation to solve for the number of days!
11.25d = 72 <em>(d = # of days)</em>
<em>Now, we have to solve this equation to see how many days (d) it will take Ms. Masi to pay her brother back.</em>
<em></em>
11.25d = 72
÷11.25 ÷11.25 (Divide by "11.25" to get the variable by itself)
d = 6.4
<em>Since, she only gets 1 pay per day, Ms. Masi will have to wait til her 7th day to pay her brother back.</em>
<em></em>
Hope this Helps! :)

Answer:
5 books per month
Step-by-step explanation:
We are trying to find a rate.
To find books per month, we would take the number of books and divide it by the number of months.
This would give us 10 books/2 months.
10/2 simplifies to 5.
Therefore the answer would be 5 books per month.
Answer:
2x+10 = 2(x+5)
5x-15 = 5(x-3)
8x+6 = 2(4x+3)
12x-8 = 4(3x-2)

Answer:
The answer to your question is
Part A. Archimedes grades 6 1/4 tests per day
Part B. 8 19/32 days
Part C. 6 26/29 days
Step-by-step explanation:
Part A
Total time = 6 2/5 days
Number of tests = 40 tests
Process
1.- Convert the mixed fraction to improper fraction
6 2/5 = (30 + 2) / 5 = 32/5
2.- Divide 40 by 32/5
40/1 / 32/5 = (40 x 5) / (32 x 1)
= 200 / 32
Simplify
100 / 16 = 50/8 = 25/4
3.- Convert 25/4 to mixed fractions
6
4 25
1
25/4 = 6 1/4
Archimedes grade 6 1/4 tests per day
Part B
15 more tests
Total time = 32/5
Total tests = 40 + 15 = 55
Process
1.- Divide 55 by 32/5
55 / 1 / 32 /5 = (55 x 5) / (32 x 1)
= 275 / 32
2.- Convert 275/32 to a mixed fraction
8
32 275
256
19
Result 8 19/32 days
Part C
1.- Divide 55 by 7.25
50 / 7.25 = 5000 / 725
6
725 5000
- 4350
650
Result 6 650/750 = 6 26/29
