Question

Some birds and squirrels were on a branch of a tree. There were 15 animals on the branch with a total of 50 animal feet. How many birds and how many squirrels were on the branch?

Part 1: Set up the problem.

Part 2: Explain why you set it up that way.

Part 3: Provide the solution.

Answer 1

donn't mind me lagrange. I'm just here for the relaxing atmosphere.

Answer 2

simple system of equations:

in total ofcourse there are 50 animal feet so:

x+y=50 (where x and y are squirrels and birds respectively)

Then second equation would be:
Keeping in mind that in this world, squirrels have 4 feet and birds have 2 feet is:

4x+2y=15. So the system ends up being:

{x+y=50}
{4x+2y=15}

Now can you solve this?

Answer 3

Yeah, Thank you so much. (:

Answer 4

just do it quietly ... don't disturb the wildlife ...

Answer 5

Typo: The first equation should be equal to 15 and the second should be equal to 50:


{x+y=15}
{4x+2y=50}
