TEAS Test Math Questions

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: D

Rationale: To find the area of a square, you square the length of one side. In this case, the side length is 75 cm. Therefore, the area is 75 cm x 75 cm = 5,625 square cm. Option D is correct. Option A (150) is too small as it represents the perimeter of the square. Option B (300) is incorrect as it is half the correct area. Option C (5,325) is incorrect as it is much larger than the correct area.

Correct Answer: D

Rationale: To simplify the expression 3x - 5x + 2, we first combine like terms. 3x - 5x = -2x, so the expression becomes -2x + 2. Thus, the correct answer is D: -2x. Choice A is incorrect as it incorrectly combines the x terms without changing their signs. Choice B is incorrect as it only considers the x terms and ignores the constant term. Choice C is incorrect as it incorrectly combines the x terms without changing their signs.

Correct Answer: A

Rationale: Correct Answer: A (2) Rationale: 1. When dividing 8 by 4, it means splitting 8 into 4 equal parts. 2. Each part would be 2, as 8 divided by 4 equals 2. 3. Therefore, the result of dividing 8 by 4 is 2. Summary: - Option B (4): Incorrect, as 8 divided by 4 is not 4. - Option C (6): Incorrect, as dividing 8 by 4 does not result in 6. - Option D (8): Incorrect, as the division of 8 by 4 does not yield 8.

Correct Answer: C

Rationale: To find the mean, sum all values and divide by the total count. For this data set, sum = 16+18+17+15+19+14+12+11+10+16+18+17 = 183. Total count = 12. Mean = 183/12 = 15.25, which makes choice C, 16, the correct answer. Choice A, 14.25, and B, 15.25, are incorrect as they do not match the calculated mean. Choice D, 17, is incorrect as it is higher than the calculated mean value.
