  • Q1

    Two numbers have a difference of 17 and a sum of 23. Which system equations can be used to determine x and y, the two numbers?

    x - y = 17 and x - y = 23

    x + y = 17 and x - y = 23

    x + y = 17 and x + y = 23

    x - y = 17 and x + y = 23

    The members of a drama club sold tickets to a school play. Each student ticket costs $5, and each adult ticket costs $7. They sold 28 more student tickets than adult tickets. The total ticket sales were $800. Which equation can be used to determine the number of adult tickets sold?

    5(s + 28) + 7s = $800

    5(a + 28) + 7s = $800

    5(a + 28) + 7a = $800

    5(s + 28) + 7a = $800
