If you have cows and chickens the total of heads is 200 and total of legs is 540 how many chickens do you have? set up a relation x + y = 200 (for the heads, each animal has only one head, right? ) 2x + 4y = 540 (for the legs, each chicken has 2 legs, cows have 4) now, you need â¦ to eliminate a fraction.

There is a theory that heifer (young female) meat is tenderest because female beef tends to have less surface fat, the fat being distributed through the meat.The densest beef is bull meat but is tough and can smell.A steer, being an neutered bull still has the density to the meat but is not producing tostesterone to give the meat that bullish quality. Bull meat and aged cow meat tend to be used more for ground-beef.hat is all a steer is. A cow is a cow and it does not point to any classification within the species. So a steer is a cow just a type. An non-castrated male cow is called a bull.
