A farmer has 45 chickens and rabbits. There are 140 legs all together . How many chickens do the farmer has? How many rabbits does a farmer have

Step-by-step explanation:

Let r represent the number of rabbits the farmer has. Then 45-r is the number of chickens. The total number of legs is then ...

  4r +2(45-r) = 140

  r +45 = 70 . . . . . . . . divide by 2 and simplify

  r = 25 . . . . . . . . . the number of rabbits

  45 -r = 20 . . . . .  the number of chickens

The farmer has 20 chickens, and 25 rabbits.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
