Let c represent the number of chickens and p represent the number of pigs.
Since chickens and pigs have one head each, 70 heads = c + p.
Since chickens have 2 legs and pigs have 4 legs, 200 legs = 2c + 4p.
Subtracting twice the first equation (140 = 2c + 2p) from the second, we get
60 = 2p
or
p = 30 pigs
Rewriting the first equation as c = 70 - p, we get c = 40 chickens.

I count 24 heads and 80 legs. How many pigs and how many chickens are out there?
Heads: P + C = 24C = 24 - PLegs: 4P + 2C = 80Substitute, from heads: 4P + 2 (24 - P) = 804P + 48 - 2P = 802P = 32P = 16C = 24-P = 8====================Check:P + C = 16 + 8 = 244P + 2C = 4(16) + 2(8) = 64 + 16 = 80 yay!
If A collection of chickens and pigs has a total of 70 legs and 26 heads How many chickens are there?
C+P=26 2C+4P=70 Therefore C=26-P Therefore 2(26-P)+4P=70 Therefore 52-2P+4P=70 Therefore 52+2P=70 Therefore 2P=18 Therefore P=9 Therefore C+9=26 Therefore C=17 There are 17 chickens.
If there are 143 heads and 478 legs how many chickens and pigs are there?
Take P to be the number of pigs and C to be the number of chickens. Because both anamals have a head, the sum of C and P is 143, or C + P = 143 Because a chicken contributes 2 legs and a pig contributes 4, C times 2 plus P times 4 equals the total number of legs, or 2C + 4P = 478 divide this equation by 2 to get C +2P = 239 Subtract the first equation from this one P = 96 plug this into the first equation C + 96 = 143 C = 47 96 Pigs and 47 chickens
Nine chickens two dogs and three cats have a total of forty legs true or false?
Chickens have two legs . Hence 9 x 2 = 18 Dogs have four legs ; Hence 2 x 4 = 8 Cats also have four legs ; hence 4 x 3 = 12 18 + 8 + 12 = 40 Hence answer is TRUE!!!!!!

When Farmer Fiona raises cows and chickens in all her animals have 20 heads and 70 legs?
Assuming that all of the animals are "normal" (no amputees, 2-headed mutations, etc.) : 15 cows (15 x 4 = 60 legs) plus 5 chickens (5 x 2 = 10 legs) gives a total of 20 heads and 70 legs.
On a farm there are chickens and three-legged-cows. There are total of 64 heads and 147 legs. How many chickens are on the farm?
Suppose there are x chickens and y cows Then heads => x + y = 64 And Legs => 2x + 3y = 147 2*Heads: 2x +2y = 128 Subtract from Legs: 19 = y Substitute in Heads: x = 45 Answer: 45 chickens.

What is the answer to this problem a farmer owns some goats and chickens he counts 144 legs on his farm the number of chickens is4 times the number of goats how many chickens are on the farm?
Let x = the number of goats (4 legs) 4x = the number of chickens (2 legs) So we have 4*x + 2*4x = 144 4x + 8x = 144 12x = 144 x = 144/12 = 12 (goats and 48 chickens) or Let's suppose that each of them have 6 legs, so there would be 24 chickens and goats (144/6), and we can say there are 12 chickens and 12 goats. But the number of chickens is 4 times the number of goats, so there are 48 chickens (4*12) and 12 goats.
