Question

at local park, there were ravens and dogs you notice that were 100 heads and 270 legs all tpgether. how many ravens were there? how many dogs were things?

Answer 1

The answer to that problem is 370

Answer 2

X+Y=100 In this case X would be Dogs and Y would be Ravens. We are told that X (dogs)+ Y (ravens) = 100. Each dog has 4 legs. 4x?=140. Each raven has 2 legs. 2x?=130. 140+130=270. ?=?=100. 35+65=100. 4x35=140, 2x65=130. 140+130=270 and 35+65=100. So we know that there are 35 Dogs and 65 Ravens making 270 legs all together and 100 heads.
