40,000 divided by 20 = 500
500 x 12 (which was 20-8)= 6,000

Answer:
Find out what x should be the apply by the power of 2 then you should be good
First, let's convert the givens to decimals to make calculations easier:
2 (3/4) = 2.75
9(5/8) = 9.625
We are given that:
Josie can hike 2.75 miles in one hour.
To know the time that Josie would take to hike 9.625 miles, we will simply do cross multiplication as follows:
2.75 miles ..........> 1 hour
9.625 miles .............> ?? hours
Time = (9.625*1) / (2.75) = 3.5 hours
A :
2.88/48 = $0.06 per ounce
B :
3.52/64= $0.055 per ounce
can be rounded to $0.06
C :
the container of 64 ounces for 3.52
or both are the same
In this problem, we have to find the factor which will
make (1 / 10) equal to (2 / 5). Therefore we can write it as:
x (1 / 10) = 2 / 5
where x is the number of people who ate the blueberries
x = (2 / 5) / (1 / 10)
x = 4
<span>Therefore 4 people ate the blueberries.</span>
