Answer:
Step-by-step explanation:
<u>Given:</u>
- Quarter = 25 ¢, number of quarters = q
- Dime = 10 ¢, number of dimes = d
- Total amount = $13.20 = 1320 ¢
<u>Required equations:</u>
- q + d = 72
- 25q + 10d = 1320
<u>Solve by elimination, multiply the first equation by 10 and subtract from the second equation:</u>
- 25q + 10d - 10q - 10d = 1320 - 10*72
- 15q = 600
- q = 600/15
- q = 40
<u>Find p:</u>
- 40 + p = 72
- p = 72 - 40
- p = 32
Answer:
495
Step-by-step explanation:
60x10=600
600-105=495
6.34x 10-1 because you take the decimal and put it in between the 6 and the 3 and then you figure out how many times destiny needs to move and if it needs moved to the left it is a negative and since it only does once it’s just -1

5+3= 8
72 / 8 = 9
9 x 3 = 27
