TEAS Test Math Questions

Correct Answer: A

Rationale: To simplify the expression 2x + 3x - 5, we combine like terms. First, add 2x and 3x to get 5x. Then, subtract 5 from 5x to get the final simplified expression: 5x - 5. Therefore, choice A is correct. Choices B, C, and D are incorrect because they do not correctly combine the like terms or subtract the constant term from the final result.

Correct Answer: C

Rationale: The correct answer is C: Zero. When two numbers are equal, their difference is always zero. This is because the distance between two equal numbers on the number line is zero. Any other choice is incorrect because a negative or positive difference implies inequality, which contradicts the premise that the numbers are equal. Choice D is also incorrect as there is sufficient information to determine the difference between two equal numbers.

Correct Answer: A

Rationale: To convert fluid ounces to gallons, we know that 128 fluid ounces = 1 gallon. Therefore, for 1,000 fluid ounces, we divide 1,000 by 128 to get approximately 7.8125 gallons (A). The correct answer is A because it correctly represents the conversion of fluid ounces to gallons. Choices B, C, and D are incorrect because they do not accurately reflect the conversion factor. B is twice the correct answer, C is four times, and D is eight times the correct conversion.

Correct Answer: A

Rationale: The perimeter of a square is calculated by adding up all four sides. Since all sides of a square are equal, the perimeter is 4 times the length of one side. In this case, the side length is 6 cm, so the perimeter would be 4*6 = 24 cm. Therefore, choice A (24 cm) is correct. Choices B, C, and D are incorrect because they do not correctly calculate the perimeter of a square with a side length of 6 cm. Choice B (12 cm) is half the correct answer, choice C (18 cm) is three-quarters of the correct answer, and choice D (36 cm) is double the correct answer.

Correct Answer: C

Rationale: To solve for x, first add 5 to both sides to isolate the variable: 3x = 21. Next, divide by 3: x = 7. Therefore, the correct answer is C (8). Choice A (7) is incorrect as the correct answer is 8. Choices B (5) and D (9) are incorrect as they are not solutions to the equation.
