Practice Math TEAS TEST

Correct Answer: A

Rationale: The correct answer is A: 3x-12. To express 'Twelve less than thrice a number,' we first represent 'a number' as x. Then 'thrice a number' is 3x. Finally, 'Twelve less than thrice a number' translates to 3x-12. Other choices are incorrect because they do not accurately represent the given expression. Choice B (12-3x) reverses the order of operations, choice C (3-12x) incorrectly multiplies instead of subtracting, and choice D (12x-3) mistakenly subtracts the number from 12 instead of subtracting 12 from the number multiplied by 3.

Correct Answer: B

Rationale: The correct answer is B: Stocks. In this scenario, stocks are the independent variable because they are being manipulated or controlled to observe the effect on other variables like production, sales, and investments. Increasing stocks is the action taken, which then leads to the changes in production, sales, and investments. On the other hand, choices A, C, and D are dependent variables as they are influenced by the changes in stocks. Sales, production, and investments are all outcomes or results of the changes in stocks. Therefore, stocks are the independent variable in this situation.

Correct Answer: D

Rationale: To find the portion each of the other three friends received, we first calculate what fraction of the pizza was left after one friend ate half. Half of the pizza is 1/2, so 1 - 1/2 = 1/2 is left. Then, we divide 1/2 equally among the three friends, giving each 1/2 ÷ 3 = 1/6. Therefore, each of the other three friends received 1/6 of the pizza. Summary: A: 1/5 - Incorrect. Not the correct division after one friend ate half. B: 1/3 - Incorrect. The correct division is not one-third after one friend ate half. C: 1/4 - Incorrect. The correct division is not one-fourth after one friend ate half.

Correct Answer: D

Correct Answer: A

Rationale: The correct answer is A: Itself. Any number raised to the power of 1 remains the same number. This is because any number to the power of 1 is equivalent to multiplying that number by 1, which does not change the value of the number. Therefore, when a number is raised to the power of 1, the result is the number itself. Summary of incorrect choices: B: One - Raising any number to the power of 1 does not always result in 1, it results in the original number itself. C: Zero - Raising any non-zero number to the power of 1 does not result in 0. D: The number multiplied by 2 - Raising a number to the power of 1 does not double the number, it remains the same.
