16)	Bruno visits a zoo and is captivated by an exhibit containing only elephants and ostrich.  He notices that there are a total of 18 heads and 36 legs.  How many of each animal is in the exhibit?

I think Bruno mis-counted. $$36\div18=2$$
So, that would mean the whole exhibit only contains Ostrich, since they have 2 legs, Elephants have 4. Even if there was 1 Elephant and 17 Ostrich, that's 38 legs.

thats what i kept getting this problem is a mess lol had me thinking i was dumb

anonymous · Answer

so equation x+y=18 and 2x+4y=36

anonymous · Answer

$$x _{1}+y _{1}=18 heads$$ Where $$x _{1}=18$$ and $$y _{1}=0$$ I guess if y represents the Elephants. $$2x _{2}+4y _{2}=36 legs$$ Where$$x _{2}=18$$ and $$y _{2}=0$$ haha
