Simplifying Algebraic Expressions

Read the following problems and solve by simplifying the expressions.  
1.  A string of length g inches is cut into two pieces.  One piece is 10 inches longer than the other.  Find the length of the shorter piece.  


2.  Kenny has m guppies and 10 angelfish.  He buys another 20 guppies and 30 angelfish.  How many fish does Kenny have now?


3.   8 + 12s - 7 - 9s + 4




Comment below to answer one or all questions.  Make sure to identify the problem you are solving.  I will not display your answers until tomorrow afternoon.  



5.0A.1  I can use parentheses, brackets, or braces in numerical (and algebraic) expressions, and evaluate with these symbols.  
5.OA.2  I can write simple expressions that record calculations with numbers, and interpret numerical (and algebraic) expressions without evaluating them.

    I chose to solve number 3. The answer is - 5 + 3s.

    I also solved number 2 and I got - 60 + m.

    3. 8 + 12s - 7 - 9s + 4 = 21s + 5
    2. Kenny has m guppies and 10 angelfish. He buys another 20 guppies and 30 angelfish. How many fish does Kenny have now? = 20m +40
    1. A string of length g inches is cut into two pieces. One piece is 10 inches longer than the other. Find the length of the shorter piece. = 2g x 11
