Answer 5

OMG, nobody that gave the right answer showed you how! You meanies!

Ok, the easiest way to do this problem is to do the math from the bottom up:

First figure out how many cats legs in each back pack: 7 little cats for every big one 7 big cats so 7x7=49 little cats per back pack, plus 7 big ones. So each back pack has 56 cats in it. 56 cats times 4 legs per cat is 224 total legs in each back pack.

Next figure out how many back packs there are: 7 girl times 7 back packs =49 back packs total.

So if there are 49 back packs and 224 total cats legs in each, 49x224=10,976 total cats legs.

Don't forget there are 7 girls on the bus so there's another 14 legs. So add 14 to 10,976 for a total of 10,990 legs. If there is a bus driver add 2 more. So the answer is:

10,990 legs without a bus driver.

10,992 legs with a bus driver.

Edit:

Sorry I realized you may need the equation as well:

a= (7x7+7)x4x7x7+14=10,990 for no driver

a= (7x7+7)x4x7x7+14+2=10,992 with driver

Answer 6

9618

49 backpacks x 49 cats= 2401x 4 legs=9604 +14 girls legs=9618

Answer 7

5504

u take and multiply 7X2 + 7X7X4X7X4+2

that covers all the girls (7x2) and the cats (7X{7X4}^2) and then u add 2 fr the bus driver

Answer 8

ok

1 girl=2 legs

4 big cats=16 legs

7 small cats=28 legs

add the cats together-44, then multiply that by the 7 backpacks(308)

so 1 girl has 310 total legs, times 7 and you get:

2170 legs,and driver-2172(final answer)

Answer 9

10990

7 girls = 14 legs

7 girls* 7 bags=49 * 7 cats= 343 * 4 legs =1372

343 cats* 7 kitts = 2401 * 4legs = 9604

9604+1372+14=10990 legs

Answer 10

14+(28*7)+(28*7)(7) = 1582  1582(7) = 11074

7 girls multiply by two to get the # of legs.

7 cats multiply by four to get 28 then multiply by 7 to get 196.

7 small cats multiply by 4 to get 28, then multiply by 7 to the second power to get 1372.

Add them together to get 1582.

Then multiply them by 7 to get the rest of the girls legs.

1582 is just for one girl

You're left with 11074.

11076 counting the bus driver

Answer 11

without the driver : 1582

with the driver : 1590

Answer 12

a lot
