<span>75 miles per hour
miles under miles and hours and hours
</span><span>75 miles -------------->1 hour
</span>30 miles ---------------->?? nhours
cross multiplication
n = 30*1/75 = 0.4 hours = 0.4 x 60= 24 minutes
B because you are looking for an equation in the problem so if it starts at 16 and you are adding 2 gallons per hour you get 16+2x. Then for the other tank you start with 20 gallons and you are loosing 3 gallons per hour so you get 20-3x. To solve the equation you make them = each other so then you have 16+2x=20-3x.
Answer:
The second option
Step-by-step explanation:
x+y=29
5x+2y=100
then y=29–x
since 5x+2y=100
then 5x+2(29–x)=100
then 5x+58–2x=100
then 3x+58=100
then 3x=100–58
then 3x=42
then x=42/3
then x=14
then y=29–14=15
For a pear, it would be 3/16 of a chance. For an orange, it would be 1/4 of a chance.
cross multiply to find your answer
x/250 = 20/100
250 X 20= 5000
5000=100x
x = 50
250 - 50 = 200
hope this helps :)
