    Word problems?

    1. Farmer Cornelious had ducks and cows. One day he noticed that the animals had a total of 12 heads and 44 feet. How many of the animals were ducks and how many of the animals were cows?


    2. The capacity of a lift is either 15 children or 11 adults. If 9 children are currently in the lift how many adults can get in?

    You have posted absolutely no effort on your own part.
    How about showing some of your workings on these?

    Re: Word problems?

    Alright I am slightly confused on how to start. For the first one he has 12 head and forty 44 feet. Duck only have 2 feet. And cows have four feet. So would I divide somehow?

    Because each animal had only one head.

    Well not from me. Sorry.
    You simply want the problem done for you.
    This is not a homework service.

    Re: Word problems?

    But there is another simpler way to solve the problem :

    Suppose the cows are,x ,then the ducks are 12-x ,can you curry on from here??.

    Also there is another way without using equations .It is called the maximum domain rule
