TEAS Test Sample Math Questions

Correct Answer: A

Rationale: The correct answer is A: All real numbers. The function f(x)=2x+5 is a linear function, which means it is defined for all real numbers. There are no restrictions on the input x, so the domain includes all real numbers. Choices B, C, and D are incorrect because they impose restrictions on the domain that are not present in the given function. Choice B limits x to be greater than or equal to 0, choice C limits x to be strictly greater than 0, and choice D limits x to be less than or equal to 0, all of which are not accurate for the function f(x)=2x+5.

Correct Answer: B

Rationale: To add 1/6 and 1/2, find a common denominator which is 6. Then, 1/6 + 1/2 = (1/6) + (3/6) = 4/6. Simplifying 4/6 gives 2/3, which is the reduced form of the sum. Choice B is correct. Choices A, C, and D are incorrect because they do not represent the correct result of adding 1/6 and 1/2 in reduced form. Option A simplifies to 9/7, Option C simplifies to 31/36, and Option D simplifies to 3/5, none of which are the correct answer.

Correct Answer: C

Rationale: The product of two irrational numbers can be either rational or irrational. To understand this, consider √2 * √2 = 2, making it rational. However, √2 * π remains irrational. Therefore, the product can be either rational or irrational, leading to choice C being the correct answer. Choice A is incorrect because the product may be rational. Choice B is incorrect as the product is not always rational. Choice D is incorrect as it does not address the possibility of the product being rational.

Correct Answer: D

Rationale: To write 0.80 as a percent, you multiply it by 100. So, 0.80 * 100 = 80%. Therefore, the correct answer is D. Choice A (40%) is incorrect because 0.80 is not equivalent to 40%. Choice B (125%) is incorrect as 0.80 is less than 100%. Choice C (90%) is incorrect because 0.80 is not equal to 90%.

Correct Answer: A

Rationale: To solve the problem 6 + 3 * 2, we must follow the order of operations (PEMDAS/BODMAS). According to this rule, multiplication should be completed first before addition. So, 3 * 2 = 6. Then we add 6 to 6 to get the final answer of 12. Therefore, the correct operation to be completed first is multiplication (Choice A). The other choices are incorrect because division and subtraction are not part of the given equation, and addition should only be done after completing multiplication in this case.
