  1. Question 1

    What is 18.63 + 11.4?

    18.63 + 11.4 = ?

    answer box

    Show answer

    30.03

    Hint: Line up the decimal points and give every number two decimal places: 18.63 + 11.40. Add column by column: 30.03.

  2. Question 2

    What percent of the bar is shaded?

    answer box%

    Show answer

    50 %

    Hint: 2 of the 4 equal parts are shaded: 2/4. 2/4 = 50/100 = 0.5 = 50%.

  3. Question 3

    What is 1/8 × 1/2?

    1/8 × 1/2

    • 1/10
    • 1/16
    • 1/5
    Show answer

    1/16

    Hint: Multiply the numerators. Multiply the denominators. Then simplify.

  4. Question 4

    What is 3 + (-18)?

    3 + (-18) = ?

    • 21
    • -15
    • -21
    • 15
    Show answer

    -15

    Hint: Different signs: subtract the sizes, 18 − 3 = 15. Keep the sign of -18, the number farther from zero. The answer is -15.

  5. Question 5

    Which expression gives the value for any term number n?

    n1234
    value8111417
    • n + 8
    • 3n + 5
    • 3n + 8
    • -3n + 5
    Show answer

    3n + 5

    Hint: The value changes by 3 each time n goes up by 1, so the rule starts with 3n. At n = 1, 3n is 3 but the table shows 8, so add 5: 3n + 5.

  6. Question 6

    Which equation matches this sentence? "Nine times a number, plus 7, equals 25."

    • 9(n + 7) = 25
    • 9n − 7 = 25
    • 7n + 9 = 25
    • 9n + 7 = 25
    Show answer

    9n + 7 = 25

    Hint: "Nine times a number" is 9n. "Plus 7" adds 7 after multiplying: 9n + 7. "Equals 25" finishes it: 9n + 7 = 25.

  7. Question 7

    A circle has a diameter of 19 cm. What is its circumference? Use 3.14 for π and round to one decimal place.

    ⭕d = 19 cm

    answer boxcm

    Show answer

    59.7 cm

    Hint: C = π × d ≈ 3.14 × 19 = 59.66. Rounded to one decimal place: 59.7 cm.

  8. Question 8

    Point A(3, 5) is translated 6 units right and 2 units down. What is the y-coordinate of its image, A′?

    answer box

    Show answer

    3

    Hint: x: 3 + 6 = 9. y: 5 − 2 = 3.

  9. Question 9

    In a circle graph of survey results, the Summer sector is 30% and stands for 120 students. How many students were surveyed in all?

    answer box

    Show answer

    400

    Hint: 30% of the total is 120, so the total is 120 ÷ 0.3 = 400. Check: 30% of 400 = 120.

  10. Question 10

    You spin this spinner (3 equal sections) and flip a coin. What is P(blue and tails)?

    • 5/6
    • 1/6
    • 2/5
    • 1/3
    Show answer

    1/6

    Hint: P(blue) = 1/3 and P(tails) = 1/2. The events are independent, so multiply: 1/3 × 1/2 = 1/6.
