  • Question 6
    300 seconds
    Q. Erin is 3 years younger than twice Alex's age. Their ages combined are 33 years. How old are Alex and Erin. If x=Erin's age and y=Alex's age, choose the system that matches the situation.
    answer choices
    x + y = 33
    y = 2x - 3
    x + y = 33
    x = 2y - 3
    x + y = 33
    x = 3 - 2y
    x + y = 3
    x = 33 - 2y

    What is the value of x in the solution for this system?
    answer choices
    x=8
    x=3
    x=11
    x=5
  • Question 8
    300 seconds
    Q. Christian had brochures printed for a new business venture. Christian originally ordered 4 boxes of black-and-white brochures and 3 boxes of color brochures, which cost a total of $134. After those ran out, Christian spent $120 on 3 boxes of black-and-white brochures and 3 boxes of color brochures. Which system represents this situation?
    answer choices
    x+y=134
    x+y=120
    3x+3y=134
    4x+3y=120
    4x+3y=134
    3x+3y=120
    7xy=134
    6xy=120

    answer choices
    1.5x+0.5y=78.5
    x+y=87
    1.5x+0.5y=78.5
    1.5x+0.5y=87
    x+y=78.5
    1.5x+0.5y=87
    x+y=78.5
    x+y=87

  • Question 14
    300 seconds
    Q. Caitlin won a bag full of money! She has 49 bills in all. She counts $1,430. There are $20 dollar bills and $50 dollar bills. How many of each bill does Caitlin have?
    WRITE a system where T= # of $20 and F = # of $50.
    answer choices
    T + F = 1430
    20T + 50F = 49
    T+ F = 49
    10T + 5F = 1430 
    T + F = 49
    20T + 50F  = 1430
    T + F = 49
    T + F = 1430
