Please help me this is due today

1. 15 (A)

2. 12 (G)

Step-by-step explanation:

1.  We can make an equation out of this...

    3x+3=48

    x is the age of Geoff which is what we are trying to find out

    We have to add 3 to both sides of the equation

    3x+3=48

         -3   -3

    we end up with 3x=45

     we then have to divide 3 by both sides because its the opposite of                

     multipling

    3x=45

         3

    we get x=15

2.   We can write a problem statement  

      (2 x 9)-6=?

       multiply 2 and 9 FIRST

       18-6=?

       your answer is 12

      Your Welcome! Have a great rest of your day! :)
