A

Step-by-step explanation:

A]

7*5 = 35+15 = 50

10*70 = 70 +14 = 85

15*7 = 105 +15 = 120

20*7 = 140+15 = 155

B]8.50*5 = 42.5

C]10*5 = 50

10*10 = 100

D] = 8*5 = 40 +10 = 50

10*8 = 80+10 = 90

constants mean the stopped points or the points on a graph that nothing is changing, hope this

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.
