ANSWER KEYS

1. Let x = 1^st number

     2x = 2^nd number

 2x+5 = 3^rd number

x+2x+2x+5 = 80

      5x         = 80-5

      5x         =   75

      5                 5
      x           = 15 is the 1^st number

2x=2(15)

    = 30 is the 2^nd number

2x+5= 2(15)+5

        = 30+5

        =35 is the 3^rd number
