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:
132
Step-by-step explanation:
The range is the highest tempreature minus the lowest so
124--8
=124+8
=132
1 yard = 3 feet
1 foot = 12 inches
So: 6 * 3 = 18 feet
And: 18 * 12 = 216 inches

Answer:
2.6 : 400 -----convert both to either grams or kg, i'm doing grams
2600 : 400 ----simplify by 200
13:2 is lowest
23,24,and 25 because you do 3x+3=72.
72-3=69
69=3x
69 ÷3 is 23
x+1=24
x+2=25
