Practice Math TEAS TEST

Correct Answer: A

Rationale: The correct answer is A: 2W + 2(W + 3). To find the perimeter of a rectangle, you add up all its sides. Given that the length is 3 units greater than the width, the length is represented as W + 3. So, the expression for the perimeter is 2W (for the width) + 2(W + 3) (for the length). This simplifies to 2W + 2W + 6, which further simplifies to 4W + 6, representing the correct perimeter expression. Summary: B: W + W + 3 is incorrect as it only adds the width twice and does not account for the length. C: W(W + 3) is incorrect as it represents the area of the rectangle, not the perimeter. D: 2W + 2(3W) is incorrect as it incorrectly combines the width and length terms in the expression.

Correct Answer: A

Rationale: Correct Answer: A Rationale: To convert Fahrenheit to Celsius, you first subtract 32 from the Fahrenheit temperature and then divide by 1.8. This is because the conversion formula is (F - 32) / 1.8. To convert Celsius to Fahrenheit, you multiply the Celsius temperature by 1.8 and then add 32. The formula for this conversion is (C * 1.8) + 32. Therefore, choice A is correct as it follows the correct conversion formulas for both Fahrenheit to Celsius and Celsius to Fahrenheit. Summary of other choices: B: Incorrect because dividing by 2 in Fahrenheit to Celsius conversion is incorrect. C: Incorrect because multiplying by 2 in Fahrenheit to Celsius conversion is incorrect. D: Incorrect because subtracting 30 in Fahrenheit to Celsius conversion is incorrect.

Correct Answer: A

Rationale: To solve for x in the equation (x/y) - z = rw, we first isolate x by multiplying both sides by y to get x - yz = rwy. Then, we add yz to both sides to get x = rwy + yz, which simplifies to x = y(rw + z). Therefore, the correct answer is A: x = y(z + rw). Choice B is incorrect as it incorrectly distributes the y term. Choice C is incorrect as it incorrectly combines the terms. Choice D is incorrect as it incorrectly subtracts z instead of adding it.

Correct Answer: A

Rationale: To correctly order the numbers from least to greatest, we start by comparing the negative numbers first. The most negative number is -271.906, followed by -193.823. Then, we move on to the positive numbers, starting with 145.884 and ending with 235.971. Therefore, the correct order is -271.906, -193.823, 145.884, 235.971 (Option A). Choice B is incorrect because it incorrectly places 235.971 before -193.823. Choice C is incorrect as it places 145.884 before -193.823. Choice D is incorrect because it swaps the positions of -193.823 and -271.906.

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.
