One day, a person went to a horse racing area. instead of counting the number of humans and horses, he counted 74 heads and 196 legs. how many humans and horses were there?
i would really appreciate if you answer this question : )

The person at the horse race counts 74 heads and 196 legs that included an unknown number of horses and humans.

Let the number of horses that he counted be H and let the number of humans be M.

As both humans and horses have one head,

H + M = 74 ...(1)

Humans have 2 legs and horses have 4 legs, this gives

4*H + 2*M = 196 ...(2)

2*(1) - (2)

=> 4H + 2M - 2H - 2M = 196 - 148

=> 2H = 48

=> H = 24

M = 50

The person counts 24 horses and 50 humans

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

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.
