TEAS Test Math Questions

Correct Answer: B

Rationale: To find the sum of 4 + 5 + 12 + 9, we add each number sequentially: 4 + 5 = 9 9 + 12 = 21 21 + 9 = 30 Therefore, the correct answer is B: 30. Option A (20), C (40), and D (50) are incorrect as they do not accurately reflect the sum of the given numbers.

Correct Answer: A

Rationale: To find the total pounds of apples Eric buys, we multiply the pounds he buys each week (5 1/2) by the number of weeks (4). 5 1/2 * 4 = 22 pounds. Thus, the correct answer is A (22 pounds). Other choices are incorrect because they do not correctly calculate the total pounds based on the given information. B, C, and D are not the correct results of multiplying 5 1/2 by 4.

Correct Answer: A

Rationale: To simplify (x^2 - y^2) / (x - y), we recognize it as a difference of squares, (x^2 - y^2) = (x + y)(x - y). Therefore, the expression simplifies to (x + y). The correct answer is A because when we divide (x + y)(x - y) by (x - y), the (x - y) terms cancel out, leaving us with x + y. Choices B, C, and D are incorrect because they do not consider the factorization of the numerator as a difference of squares, leading to incorrect simplifications.

Correct Answer: A

Rationale: To calculate how many times larger the first cell is compared to the second, we divide the diameter of the first cell by the diameter of the second cell: 0.1 / 0.05 = 2. Therefore, the correct answer is A: 2. Option B, C, and D are incorrect because they do not accurately represent the ratio between the two cell sizes based on the given diameters.

Correct Answer: A

Rationale: To solve the inequality x > 5, we want to find all values of x that are greater than 5. This means x can be any number larger than 5 but not equal to 5. So, the correct answer is A. Choices B, C, and D are incorrect because they represent x being less than, greater than or equal to, and less than or equal to 5, respectively, which do not satisfy the original inequality x > 5.
