For each sentence, write an equation. Solve the equation to find the number a) Add 1 to a number divided by -3 and the sum is 6.
b) subtract a number divided by 9 from 3 and the difference is 0
c) add 4 to a number divided by -2 and the sum is -3

a) x=-15

b) x= 27

c) x=14

Step-by-step explanation:

a)  x/-3+1=6       x/-3=5           (-3)x/-3=5(-3)                 x=-15

          -1   -1

b) 3-x/9=0         -x/9=-3          (-9) -x/9=-3(-9)            x=27

  -3        -3

c) x/-2+4=-3        x/-2= -7       (-2)x/-2= -7(-2)          x=14    

         -4   -4

ratio is 2 : 9

the answer is three

13.5 : 3
