Algebra and Geometry: practice questions
Our Praxis Core bank has 64 questions on this topic. Here are 5 of them with answers; the full mock exam draws from every topic, like the real one.
Question 1
What are the solutions of x² = 49?
- x = 7 only
- x = 24.5
- x = 7 or x = −7
- x = 49 or x = −49
- x = −7 only
Show the answer
C. x = 7 or x = −7 — Both 7² and (−7)² equal 49.
Question 2
A circle has a radius of 5 cm. What is its area? (Use π ≈ 3.14)
- 31.4 cm²
- 15.7 cm²
- 314 cm²
- 78.5 cm²
- 25 cm²
Show the answer
D. 78.5 cm² — A = πr² ≈ 3.14 × 25 = 78.5.
Question 3
What is the slope of the line through (1, 2) and (5, 10)?
- 2
- 1/2
- 8
- 4
- 3
Show the answer
A. 2 — (10 − 2) ÷ (5 − 1) = 8 ÷ 4 = 2.
Question 4
Using C = 60 + 45h, how many hours did a job take if the bill was $240?
- 3
- 4.5
- 5
- 4
- 5.3
Show the answer
D. 4 — 240 − 60 = 180; 180 ÷ 45 = 4.
Question 5
A circle has a diameter of 10 in. What is its circumference? (Use π ≈ 3.14)
- 15.7 in
- 78.5 in
- 62.8 in
- 314 in
- 31.4 in
Show the answer
E. 31.4 in — C = πd ≈ 3.14 × 10 = 31.4.
