There are 16 animals in a farmhouse. Some of them are chickens and the others are cows. Altogether, these animals have 60 legs. How many chickens and how many cows are in the farmhouse? -- Which two equations would you use to solve this problem? Chickens have 2 legs and cows have 4 legs.

Please mark as brainliest!!

There are 2 chickens and 14 cows.

Equations:

2x + 4y = 60

x + y = 16

Step-by-step explanation:

2x + 2y = 32

Substituting now:

32 + 2y = 60

2y = 28

y = 14

x = 16 - 14 = 2

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

no not all of them.

step-by-step explanation:

some of them have a square base.
