Set up a ratio of known to unknown:
Let X = the amount of gas needed for 500 miles:
220/12 = 500/x
Cross multiply:
220x = 6000
Divide both sides by 220:
X = 6000 / 220
x = 27.27 gallons (round answer as needed).
Property of Addition and division.
Answer: 3
Step-by-step explanation:
4x+23=7x+14
4x-7x=14-23
-3x=9
x=9/3
x=3
Answer:
Step-by-step explanation:
Use cosine:
We have:
Substitute:
<em>cross multiply</em>
<em>divide both sides by 9063</em>
Answer:
You know that negative 3 1/2 is the lowest number so you would put that first. The greatest number would be the coldest in Celsius, and 1/20 would be the last question (the sea level) if calculations are correct, you would get full credit.
