Try the two algebra and geometry questions below, then ask QuizGen for more practice on the topics you missed. These are original practice questions, not official SAT questions.
Solve each question before opening the answer. These two examples review basic skills; they do not represent the difficulty or scope of a full SAT test.
A school club pays $24 to reserve a room and $6 for each member who attends. The total cost is $90. How many members attend?
- 9
- 11
- 15
- 19
Show algebra answer and steps
Answer: B. 11 members. Let n be the number of members. The room fee plus the cost per member gives 24 + 6n = 90. Subtract 24 to get 6n = 66, then divide by 6 to get n = 11. Check: 24 + 6 × 11 = 90.
A right triangle has legs of length 9 and 12. What is the length of its hypotenuse?
- 15
- 18
- 21
- 25
Show geometry answer and steps
Answer: A. 15. By the Pythagorean theorem, c² = 9² + 12² = 81 + 144 = 225. A length is positive, so c = √225 = 15. The hypotenuse is longer than either leg, which is consistent with 15.
