HiSET - High School Equivalency Test Practice Test Math 1 — Questions and Answers
Question 1: Solve for x: 2x + 9 = 25
- 6
- 7
- 8 (Correct answer)
- 17
Correct answer: 8
Subtract 9 from both sides to get 2x = 16, then divide both sides by 2 to get x = 8.
Question 2: A data set contains the values: 3, 8, 5, 12, 7, 9, 5. What is the mode?
- 5 (Correct answer)
- 7
- 8
- 9
Correct answer: 5
The mode is the value that appears most often. The number 5 appears twice while all other values appear only once, so 5 is the mode.
Question 3: A rectangle has a length of 10 cm and a width of 4 cm. What is its area?
- 28 cm²
- 40 cm² (Correct answer)
- 14 cm²
- 80 cm²
Correct answer: 40 cm²
Area of a rectangle = length × width = 10 × 4 = 40 cm².
Question 4: A car travels 180 miles in 3 hours. What is its average speed in miles per hour?
- 45 mph
- 55 mph
- 60 mph (Correct answer)
- 540 mph
Correct answer: 60 mph
Average speed = total distance ÷ total time = 180 ÷ 3 = 60 mph.
Question 5: What is 40% of 75?
- 25
- 30 (Correct answer)
- 35
- 40
Correct answer: 30
Convert 40% to a decimal (0.40) and multiply by 75: 0.40 × 75 = 30.
Question 6: What is the value of y if y = 3x − 4 and x = 5?
- 7
- 9
- 11 (Correct answer)
- 19
Correct answer: 11
Substitute x = 5 into the equation: y = 3(5) − 4 = 15 − 4 = 11.
