TEAS Test Math Questions

Correct Answer: D

Rationale: To determine the correct answer, we need to find the value of x in each proportion. For choice A, x = 4; for choice B, x = 8; for choice C, x = 6; and for choice D, x = 10. So, the correct answer is D because it yields a different value for x compared to the other choices. Choices A, B, and C all have x values that are multiples of 2, whereas choice D has a different x value. Therefore, choice D is the only proportion that yields a different number for the unknown compared to the others.

Correct Answer: A

Rationale: To find the product of 2/3 and 3/4, multiply the numerators (2 * 3 = 6) to get the new numerator and multiply the denominators (3 * 4 = 12) to get the new denominator. Therefore, the product is 6/12 which simplifies to 1/2. Choice A (1) is correct because 1 is the simplified form of the product. Choices B, C, and D are incorrect as they do not reflect the correct multiplication of fractions.

Correct Answer: B

Rationale: To find the difference between two negative numbers, we subtract the second negative number from the first. When we subtract a negative number from another negative number, it is equivalent to adding the positive value of the second number to the first number. This results in a positive number as the answer, making choice B (Positive number) the correct answer. Choices A, C, and D are incorrect because the result of subtracting two negative numbers is always a positive number, not another negative number, zero, or not enough information.

Correct Answer: B

Rationale: To solve the system of equations, we can use either substitution or elimination method. By substituting y = -2x into the second equation, we get x - 2(-2x) = 8, which simplifies to 5x = 8, leading to x = 8/5. Substituting x back into the first equation, we find y = -16/5. Therefore, the correct solution is (1.6, -3.2). Option B (1.8, -3.6) and (-1.8, 3.6) is incorrect as it does not match the calculated solution. Options A, C, and D are also incorrect as they do not correspond to the solutions obtained through the correct calculations.

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.
