Question 1
What is 3 + (-18)?
3 + (-18) = ?
- 21
- -15
- -21
- 15
-15
Hint: Different signs: subtract the sizes, 18 − 3 = 15. Keep the sign of -18, the number farther from zero. The answer is -15.
Question 2
What is 8 × 6?
8 × 6 = ?
answer box
48
Hint: Split 8 into 5 + 3: 6 × 5 = 30 and 6 × 3 = 18. Add them: 48.
Question 3
What is 18.63 + 11.4?
18.63 + 11.4 = ?
answer box
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.
Question 4
What percent of the bar is shaded?
answer box%
50 %
Hint: 2 of the 4 equal parts are shaded: 2/4. 2/4 = 50/100 = 0.5 = 50%.
Question 5
Two stores sell the same scooter. Which store has the lower sale price?
Store Regular price Sale A $90.00 25% off B $120.00 10% off - Store B
- They cost the same
- Store A
Store A
Hint: Store A: pay 75% of $90.00 = $67.50. Store B: pay 90% of $120.00 = $108.00. Store A is cheaper.
Question 6
Point A(3, 5) is translated 6 units right and 2 units down. What is the y-coordinate of its image, A′?
answer box
3
Hint: x: 3 + 6 = 9. y: 5 − 2 = 3.
Question 7
Which expression gives the value for any term number n?
n 1 2 3 4 value 8 11 14 17 - n + 8
- 3n + 5
- 3n + 8
- -3n + 5
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.
Question 8
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
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.
Question 9
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 cmanswer boxcm
59.7 cm
Hint: C = π × d ≈ 3.14 × 19 = 59.66. Rounded to one decimal place: 59.7 cm.
Question 10
A cylinder's circular base has an area of 78.5 cm². The cylinder is 4 cm tall. What is its volume?
- 985.96 cm³
- 314 cm³
- 82.5 cm³
- 157 cm³
314 cm³
Hint: Volume = base area × height = 78.5 × 4 = 314 cm³. The base area already includes π, so don't multiply by 3.14 again.
