Answer:

  • 16 chickens
  • 12 horses

Step-by-step explanation:

You have 28 horses and chickens with a total of 80 legs, and you want to know the number of each kind of animal.

Setup

Let h represent the number of horses. Then 28-h is the number of chickens, and the total number of legs is ...

  4h +2(28-h) = 80

Solution

Simplifying the equation, we get ...

  2h +56 = 80

  h +28 = 40 . . . . . . . divide by 2

  h = 12 . . . . . . . . . . subtract 28

  28 -h = 16 . . . . . find the number of chickens

There are 16 chickens and 12 horses in the pasture.

Answer:

The correct answer is 16 and 12

Step-by-step explanation:

  • Total number of heads = 28
  • Total number of legs = 80

There are 28 horses and chickens and 80 legs:

[tex]a + b = 28 ........ Eq12a + 4b = 80 ...... Eq 2From Eq1 and Eq2b = 12a = 16[/tex]

How many chickens and cows in the field?

There are 30 cows in the field, 28 chickens. How many didn’t? Yes, this is worded correctly. But it’s also worded confusingly to throw you off.

[tex]2h +56 = 80 h +28 = 40 divide by 2 h = 12 subtract 28[/tex]

[tex]28 -h = 16[/tex]

So, your answer is 16 and 12
