  • Use the distributive property on 10(3 + 45x) + 9(2y - 9) to create an equivalent expression
    30 + 450x + 18y - 81
  • Combine like terms to create an equivalent expression: 8.3(y + 1) + 1.7y - 0.3
    10y + 8
  • Expression: 7x + 3(9 + x), find the answer when x = 5
    77
  • Factor 55 - 5k (using the greatest common factor) to create an equivalent expression
    5(11 - k) OR 5(11 - 1k)
  • Use the distributive property on 100(3.50 + 8y) to make an equivalent expression
    350 + 800y
  • create an equivalent expression to 8x + 7(x - 1) + 87
  • Your parents give you 80 aed a month as an allowance If you already have 480 aed, write an expression that shows how much aed you have after M months. Then another team member has to solve for your allowance after 12 months
    80M + 480 OR 480 + 80M ; 1,440 aed
  • Are -3 - 11y + 3 - 4y and -15y equivalent?
    Yes
  • Are 5(6y + 7) and 30y + 35 equivalent
    yes
  • Combine like terms to create an equivalent expression: 10 -6y + 55 -4y
    65 - 10y or -10y + 65
  • The volume of a rectangular prism is given shown with the expression Volume = LWH. Find the volume of the rectangular prism when L=11, W=3, H=4
    132
  • Your apple tree started out with 10 apples on it. It grows 7 apples a day. Write an expression that shows how many apples are on the tree after D days. Then another team member has to solve for the number of apples after 9 days.
    10 + 7D OR 7D + 10; 73 apples

    34
  • Are 6 + 4y - 6 and 12 + 4y equivalent?
    No
  • Factor 10b + 10 (using the greatest common factor) to create an equivalent expression
