ziggy has some hens and some rabbits. together, these animals have 50 heads and 140 feet. how many hens and how many rabbits does ziggy have
h + r = 50 2h + 4r = 140. Solvable system.
|dw:1352768244651:dw|
i find it hard to pick any information from the problem other than the fact that rabbits have 4 feet and hens have 2 feet
NP. Start with 50 heads. Each animal has one and only one (I hope!) so that's where the first equation comes into play.
|dw:1352768507998:dw| this is what i have as of now
You basically conceptualized the second equation I wrote out for you. You seem to like the chart more than the equations. You will eventually have to work the equations, but we can start with the chart. In box hens, # of animals, you put "h" and off to the right side box, you have 2h.
For rabbits, the lower left box is "r" and the lower right box is "4r"
|dw:1352768715171:dw| so like this?
and then it would be 2h+4r=140?
|dw:1352768795000:dw|Yes, and then I added a little bit more for you now.
