A mistake was made in the steps shown to simplify the expression. Which step includes the mistake? 1792 + |-101 = 2
Step 1: = 1 + 32 + 10 = 2
1 + 9
Step 2: =
5 + 10 = 2
Step 3: = 1 + 10 = 2
Step 4: = 2 + 10 = 2
Step 5: = 12 - 2
Step 6: = 6
A.
Step 4
B. Step 5
C. Step 1
D. Step 3

the 4th choice is the correct one

step-by-step explanation:

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.
