Answer:
keiko- x
imelda- x+ 36
Sarah- x- 38
Step-by-step explanation:
- keiko is x since we have not been given his number of boxes.
- because imelda's number of boxes was 36 <em>more </em><em>than </em>keiko's, you will add the x which is for keiko and 36 for imelda(x+36).
- and sarah's number of boxes will be x-36 because we have been told her number of boxes is 38 <em>fewer </em><em>than </em> keiko's.

it is already fikled ok
Step-by-step explanation:
Step-by-step explanation:
So you have 31/40
3/4=30/40 (multiply by 10/10)
4/5=32/40 (multiply by 8/8)
So, there you have it, 31/40 is right in between those two.
turn it into decimal format. just do the division,. 31 divided by 40 = .775 and 3 divided by 4 = .75 and 4 divided by 5 = .8. all you have to do is the division and once it is in decimal format you can tell which is greater. hope this helps
Speed of truck= x
speed of train=x-30
A loaded moving truck is traveling 30 mph faster than a freight train. in the time it takes the train to travel 135 miles, the truck travels 225 miles. find the speed of the truck.
A loaded moving truck is traveling 30 mph faster than a freight train...
(x-30)=speed of train
the time it takes the train to travel 135 miles, the truck travels 225 miles...
135/(x-30)=225/x
the you multiply on both sides the x values and get...
135x=225x-6750
then you subtract 225x on both sides...
-90x=-6750
then you divide -90 on both sides...
x=75
the speed of the truck is 75mph
