TEAS Test Math Questions

Correct Answer: C

Rationale: To solve 3x + 2 = 20, first subtract 2 from both sides to isolate 3x. This gives 3x = 18. Then divide by 3 to solve for x, yielding x = 6. Choice C is correct because 3(6) + 2 equals 20. Choices A, B, and D are incorrect because they do not satisfy the original equation when substituted back in.

Correct Answer: A

Rationale: To evaluate -3 x 5, we multiply -3 by 5 which gives us -15. The correct answer is A (-15) because when multiplying a negative and a positive number, the result is negative. Choice B (-2) is incorrect as it is the result of adding -3 and 5. Choice C (2) is incorrect as it is the result of multiplying -3 and -5. Choice D (15) is incorrect as it is the result of multiplying 3 and 5, not -3 and 5.

Correct Answer: C

Rationale: The mode is the value that appears most frequently in a data set. In this case, the number 4 appears three times, which is more frequent than any other number in the set. Therefore, the mode of the data set is 4 (Choice C). The other choices (A: 2, B: 3, D: 5) are incorrect because they do not appear as frequently as 4 in the given data set.

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: C

Rationale: The correct answer is C because in multiplication and division, the product of the quotient and the divisor is indeed the dividend. To understand this, consider a division problem like 12 ÷ 3 = 4. Here, 4 (quotient) multiplied by 3 (divisor) equals 12 (dividend). Therefore, the product of the quotient and the divisor equals the dividend. Choice A is incorrect as it doesn't align with the relationship between quotient, dividend, and divisor in division. Choice B is incorrect as it reverses the relationship between dividend and divisor in multiplication. Choice D is incorrect as there is a correct statement among the choices.
