Of the 60 animals on a certain farm, 2/3 are either pigs or cows. how many of the animals are cows? (1) the farm has more than twice as many cows as pigs (2) the farm has more than 12 pigs.

Step-by-step explanation:

either cow or pigs

Either pigs or cow = 40

(1) Let number of pigs be x

   then number of cows >twice of pigs = 2x

    number of pigs + number of cows  = 40

                number of cows = 40 -x

                   40-x > 2x

                   40 > 3x

               x <

               x < 12.33

               nearest integral number is 12

               so its 12

              so number of pigs will be 12 so that number of cows = 40 -12 = 28

           which is more than twice of number of pigs

             28 > 2( 12)  = 24

     (2)   number of pigs + number of cows = 40

        for x>12

               number of cows = 40 -x

                  x > 12

                 -x < -12

             adding 40 both sides

            40-x < 40-12

           number of cows <28

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint
