Simplifying Algebraic Expressions


Write an expression for each situation.  Simplify the expression.  





1.  John has y stickers.  He keeps 20 stickers for himself and gives the remainder to his two sisters equally.  How many stickers does each sister get?



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.

    1. y-20/2=y-10
    2. m+10+20+30=m+60
    3. 8+12s-7-9s+4
    1+12s-9s+4 5+12s-9s=5+3s
