  1. Which equation represents the relationship: 'a number tripled, then decreased by 4, equals 11'?

    Answer: 3n - 4 = 11

    Tripling a number gives 3n, and decreasing by 4 gives 3n - 4 = 11.

  2. What is the value of x if 5x + 3 = 28?

    Answer: 5

    Subtracting 3 from both sides gives 5x = 25, so x = 5.

  3. A function rule states f(n) = 4n − 1. What is f(7)?

    Answer: 27

    f(7) = 4(7) − 1 = 28 − 1 = 27.

  4. Which table of values matches the rule y = 2x + 5?

    Answer: x=1,y=7; x=2,y=9; x=3,y=11

    When x=1: 2(1)+5=7; x=2: 2(2)+5=9; x=3: 2(3)+5=11.

  5. If the pattern of triangles follows the sequence 1, 4, 7, 10, …, what expression gives the nth term?

    Answer: 3n − 2

    The sequence increases by 3 each time, and the first term is 1, giving 3n − 2.

  6. Two students earn the same weekly pay. Maria works 8 hours and earns $72. How much does Carlos earn if he works 5 hours at the same rate?

    Answer: $45.00

    The hourly rate is $72 ÷ 8 = $9, so 5 × $9 = $45.

  7. Which inequality is represented by 'a number is at most 15'?

    Answer: n ≤ 15

    'At most 15' means the number can equal 15 or be less, written as n ≤ 15.
