Answer:
449 per hour
Step-by-step explanation:
First of all we know the question is asking us to round to the nearest tenth and find the rate of gallons per hour.
First:
Know there are 60 minutes in one hour
Second:
Take 7.48 and multiply it by 60
Third:
This should give you---448.8
Which is correct, but we are not done
Fourth:
Round to the nearest whole number
448.8
8 is closer to 10 than it is to 1 so we add 0.2
Which gives us 449
Five:
Just add the "per hour"
Six:
Your answer is---449 per hour---
-10=10(k-9)
so,
-10=10k-90
that is just expanding the brackets by multiplying to k and-9
then.
-10=10k-90
move the-90 over by adding 90
so, 80=10k
k =80/10
k=8
The answer should be D. 47/30
