Helen is filling a pool that holds 10 1/2 gallons for her little brother. she can carry 1 7/8 gallons of water each trip. write and solve an equation to find how many trips helen needs to make.

The equation is given by

y=1 x

where y is the amount of water is the pool and x is the number of trips Helen has made.

To fill the pool, Helen must make 6 trips.

Step-by-step explanation:

The amount of water is the pool y is given by

y=1 x

where x is the number of trips Helen has made. If we wish to find out how many trips she needs to make to fill 10 1/2 gallons in the pool, we solve for x:

y = 10 1/2 = 1 x

10 1/2 = 10.5 and 1    = 1.875. Thus,

10.5 = 1.875 x

x =

= 5.6

Since 5.6 trips makes no sense, we must round up to 6.

Thus, the answer is 6 trips.

a = 11 : 4

b = 38

c = 1 for every 6

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
