Answer:
10 packs of markers
Step-by-step explanation:
3 x 25 = 75 markers she will need for her whole class
75 / 8 = 9.4 packages needed to get 75 markers, but since you cant buy have of a pack you round up so she will have enough for her class and a couple extra.
100 miles in 4 hours. The unit rate would be 25 miles per hour.
100miles / 4hrs = 25 miles per hour
Therefore, for every hour you travel, you will gain 25 miles. Or for every 25 miles you travel, you've spent 1 hour traveling it.
y = 25x
where y is the total miles traveled, 25 is the constant unit rate, and x is the number of hours traveled.
for example: you traveled for 8 hours and you want to know how long you've traveled while maintaining the rate of 25mph. Just use the formula
y = 25x
y = 25(8)
y = 200 miles. you have traveled 200 miles in 8 hours.
Answer:
x = 
Step-by-step explanation:
Given
Ax + By = C ( isolate the term in x by subtracting By from both sides )
Ax = C - By ( divide both sides by A )
x =
