Sample ACT Math Practice Questions with Answers
Below are several practice questions covering different topics in the ACT Math section, complete with detailed solutions.
Question 1: Algebra — Solving for x
If 3x - 7 = 2x + 4, what is the value of x?
Answer:
- Subtract 2x from both sides:
3x - 2x - 7 = 4
- Simplify:
x - 7 = 4
- Add 7 to both sides:
x = 11
Solution Explanation:
This is a straightforward linear equation. Isolating x by combining like terms and then solving yields x = 11.
Question 2: Geometry — Area of a Triangle
A triangle has a base of 10 units and a height of 6 units. What is the area of the triangle?
Answer:
Use the formula for the area of a triangle:
\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]
\[ \text{Area} = \frac{1}{2} \times 10 \times 6 = 5 \times 6 = 30 \text{ square units} \]
Solution Explanation:
Applying the standard area formula for triangles is essential. Multiplying half the base times the height gives the correct area.
Question 3: Coordinate Geometry — Distance Between Two Points
What is the distance between the points (3, 4) and (7, 1)?
Answer:
Use the distance formula:
\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]
\[ d = \sqrt{(7 - 3)^2 + (1 - 4)^2} = \sqrt{4^2 + (-3)^2} = \sqrt{16 + 9} = \sqrt{25} = 5 \]
Solution Explanation:
The distance formula is derived from the Pythagorean theorem. Plugging in the coordinates gives the straight-line distance.
Question 4: Trigonometry — Basic Sine Calculation
In a right triangle, one of the non-right angles measures 30 degrees. If the hypotenuse is 10 units, what is the length of the side opposite the 30-degree angle?
Answer:
Since sine of 30° is 0.5:
\[ \sin 30^\circ = \frac{\text{opposite}}{\text{hypotenuse}} \]
\[ 0.5 = \frac{\text{opposite}}{10} \]
\[ \text{opposite} = 0.5 \times 10 = 5 \text{ units} \]
Solution Explanation:
Using basic trigonometric ratios helps find missing side lengths in right triangles efficiently.
Question 5: Word Problem — Combining Multiple Skills
A store is having a 25% off sale on all items. If a jacket originally costs $80, and there is an additional 10% sales tax, what is the total cost of the jacket after the discount and tax?
Answer:
- Calculate the discount:
\[ \$80 \times 0.25 = \$20 \]
- Subtract the discount:
\[ \$80 - \$20 = \$60 \]
- Calculate the sales tax:
\[ \$60 \times 0.10 = \$6 \]
- Add the tax to the discounted price:
\[ \$60 + \$6 = \$66 \]
Final Answer: \(\boxed{\$66}\)
Solution Explanation:
This question combines percentage calculations with basic addition, testing your ability to manage multi-step problems.

Sample ACT Math Practice Questions with Answers
Below are carefully selected sample questions spanning different topics, each accompanied by detailed solutions.
Question 1: Algebra - Linear Equations
Solve for x: 3x - 7 = 2x + 4.
Answer and Explanation:
- Subtract 2x from both sides:
3x - 2x - 7 = 4
- Simplify:
x - 7 = 4
- Add 7 to both sides:
x = 4 + 7
- Final answer:
x = 11
Question 2: Geometry - Triangle Properties
In a triangle, one angle measures 50°, and the second angle measures 60°. What is the measure of the third angle?
Answer and Explanation:
- The sum of angles in a triangle is always 180°.
- Sum of known angles:
50° + 60° = 110°
- Subtract from 180°:
180° - 110° = 70°
- Third angle = 70°
Question 3: Trigonometry - Basic Identities
If sin θ = 3/5 and θ is in the first quadrant, find cos θ.
Answer and Explanation:
- Use the Pythagorean identity:
sin² θ + cos² θ = 1
- Plug in sin θ:
(3/5)² + cos² θ = 1
- Calculate:
9/25 + cos² θ = 1
- Subtract 9/25 from both sides:
cos² θ = 1 - 9/25 = 25/25 - 9/25 = 16/25
- Take the positive square root (since θ is in the first quadrant where cosine is positive):
cos θ = 4/5
- Answer: cos θ = 4/5
Question 4: Arithmetic - Percent Increase
The price of a jacket was decreased by 20%. If the new price is $80, what was the original price?
Answer and Explanation:
- Let the original price be P.
- After a 20% decrease:
New price = P - 0.20P = 0.80P
- Set equal to $80:
0.80P = 80
- Solve for P:
P = 80 / 0.80 = 100
- Original price = $100
Question 5: Data Analysis - Probability
A bag contains 3 red, 5 blue, and 2 green marbles. If one marble is drawn at random, what is the probability it is either red or green?
Answer and Explanation:
- Total marbles:
3 + 5 + 2 = 10
- Red or green:
3 (red) + 2 (green) = 5
- Probability:
5 / 10 = 1/2
- Answer: 1/2

Question 6: Algebra and Functions
If f(x) = 2x² - 3x + 4, find f(3).
Answer and Explanation:
- Substitute x = 3:
f(3) = 2(3)² - 3(3) + 4
- Calculate:
2(9) - 9 + 4 = 18 - 9 + 4 = 13
- f(3) = 13
Question 7: Geometry - Circle Theorem
In a circle, the measure of an inscribed angle is 40°. What is the measure of the intercepted arc?
Answer and Explanation:
- The measure of an inscribed angle is half the measure of its intercepted arc.
- Therefore, intercepted arc = 2 × 40° = 80°
- Answer: 80°
Question 8: Trigonometry - Solving for θ
Given that cos θ = 0.6 and θ is in the second quadrant, find sin θ.
Answer and Explanation:
- Use the Pythagorean identity:
sin² θ + cos² θ = 1
- Plug in cos θ:
sin² θ + (0.6)² = 1
- Calculate:
sin² θ + 0.36 = 1
- Subtract 0.36:
sin² θ = 0.64
- Since θ is in the second quadrant, sin θ is positive:
sin θ = √0.64 = 0.8
- Answer: sin θ = 0.8
