Allison has 5 times as many baseballs cards as football cards. in all ,she 120 baseball and football cards. how many baseball cards does allison have

well to help you solve this problem you should set an equation as so...

B=5F

B+F=120

Next you would plug in what B equals into the equation B+F=120 like so

5F+F=120

then you add like terms

6F=120

then you isolate the variable by dividing like so

6F=120

F=20

so Allison has 20 football cards and you would subtract 20 from 120

120-20=100

so Allison has 100 baseball cards

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
