Answer:
=2.3576x
Step-by-step explanation:
0.421x(5.6)
=2.3576x
Gallon of gas be x
4x=20
x=5
per gallon=32m
with 5 gallon=32*5=160
The easiest way to do a problem like this is to think about the fact that you have 100% and you want to add another 85%.
This is 185% of the quantity that you have.
Multiply 250 by 185% or 1.85.
250 * 1.85 = 462.5 ml
400 quarters
$1 = 4q
4q • 100 = 400
400q=$100
105 m = 2.5 h
x miles = 1 hour
You cross multiply since it's a proportion:
2.5 * x
105 * 1
=
2.5x = 105
Then you divide everything by 2.5
The answer is 42
