The questions i need is 8 and 9, you!

8. 140

9. 781

Step-by-step explanation:

8. so cut the boxes in half and when you do this you get for the lower box 24 and 12 so for the lower box you do 2 x 24 + 12. For the upper box you get 17 and 29 so for the upper box you do 17 x 2 + 29 + 17. then you add these two together and get 140. 60 + 80 = 140

9. the lower half 12 x 24 = 288 then the upper half 17 x 29 = 493 then 288 + 493 = 781

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.
