TEAS Exam Math Practice

Correct Answer: B

Rationale: The correct answer is B because when simplifying the expression 14 - 7 + (-7), we get 14 - 7 - 7 = 0, which is not a negative value. A: (-3)(-1)(2)(-1) simplifies to 6, which is a positive value. C: 7 - 10 + (-8) simplifies to -11, a negative value. D: -5(-2)(-3) simplifies to -30, a negative value. Thus, B is the only choice that results in a non-negative value.

Correct Answer: D

Rationale: To calculate the percentage of questions answered correctly, divide the number of correct answers by the total questions and multiply by 100. In this case: (42/48) x 100 = 87.5%. Therefore, choice D (87.50%) is correct. Choice A (1.14%) is too low. Choice B (82.50%) is close but incorrect. Choice C (85.00%) is also close but not the accurate percentage.

Correct Answer: C

Correct Answer: B

Rationale: To simplify the expression, we follow the order of operations (PEMDAS). First, we calculate the exponents: 52(3) + 3(-2)^2 / 4 + 9 - 2(5-8) = 156 + 3(4) / 4 + 9 - 2(3) = 156 + 12 / 4 + 9 - 6. Then, we perform division and multiplication from left to right: 156 + 3 + 9 - 6 = 168. Therefore, the correct answer is 87/19. Choices A, C, and D are incorrect as they do not correctly simplify the expression following the order of operations.

Correct Answer: D

Rationale: To calculate Matt's new wage, we need to add the 3/20 increase to his original wage w. So, the new wage is w + 3/20w = 23/20w = 1.15w, which corresponds to choice D. Choice A is incorrect as it represents a decrease. Choice B is incorrect as it represents a smaller increase. Choice C is incorrect as it represents a larger increase than what Matt received.
