One cat has four paws, so there are 120/4=30 cats. If a "set" of cats is two uncool cats and three cool cats, there are five cats in a set, so there are 30/5=6 sets. Since each of the six sets contains three cool cats, there are 18 cool cats in the family.
Y =0.5x +2 The y-intercept is found by the coordinates (0,2) and the change is 0.5
Its is two since you take out the decimals then divide regularly
