A farmer counts 70 heads and 200 legs how many chickens and pigs does he have?
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 get60 = 2porp = 30 pigsRewriting 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!
A collection of cats and dogs and birds has a total of 76 heads and 260 legs between them There are twice as many cats as there are dogs how many of each is there?
18 cats,22 birds and 36 dogs....
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!!!!!!
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

There are 42 chickens in the farm.
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.
On a farm there are chickens and horses There are total of 59 heads and 190 legs How many chickens are on the farm?
there are 36 horses and 23 chickens.........
The teacher noticed that there were a total of 100 heads and 270 legs how many chickens were there how many pigs were there?
35 pigs, 65 chickens
On a farm there are horses and chickens there are total of 71 heads and 264 legs how many horses are on the farm?
There are 61 horses and 10 chickens on the farm.
The dairy farm has both cows and chikensThe farm workers counted 50 legs and 18 heads how many cows are in the farm and how many chickens?
7 cows and 11 chickens. Cows have 4 legs. Chickens have 2 legs. (4 legs)(7 cows) + (2 legs)(11 chickens) = 50 legs. 7 cow heads = 11 chicken heads = 18 heads.
On a farm there are horses and chickens there are a total of 27 heads and 92 legs how many horses are on the farm?
27
On a farm there are horses and chickens There are total of 107 heads and 392 legs How many horses are on the farm?
If all were horses there would be 428 legs. The shortfall of 36 legs represents 18 chickens so there are 89 horses.
How many rabbits and chickens are there if there were 35 heads and 94 legs?
Let the number of rabbits be ( r ) and the number of chickens be ( c ). The total number of heads gives us the equation ( r + c = 35 ), and the total number of legs gives us ( 4r + 2c = 94 ). Solving these equations, we find that there are 23 chickens and 12 rabbits.
On a farm there are three legged cows and chickens there are a total of 48 heads and 122 legs how many three legged cows are there?
Do-it-in-your-head method: If all animals were chickens there would be 96 legs. There are 26 extra legs, each on a cow, so there are 26 cows and therefore 22 chickens.
