TEAS Practice Test Math

Correct Answer: A

Rationale: To find the expression for the length of the rectangle in terms of x, we first note that the length is six less than two times the width. Therefore, the expression for the length would be 2x - 6. This is because the length is equal to 2 times the width (2x) minus 6. Therefore, option A (2x - 6) is the correct answer. Option B (6-2x) is incorrect because it represents the width minus 2 times the width, which is not the correct relationship. Option C (6x-2) is incorrect because it represents 6 times the width minus 2, which is not the correct relationship. Option D (3x-4) is incorrect because it represents 3 times the width minus 4, which does not match the given relationship between the length and the width.

Correct Answer: D

Rationale: To find the number of blue gumballs, we first calculate the percentage of blue gumballs: 100% - (20% + 30% + 5% + 10%) = 35% blue gumballs. Since there are 120 gumballs in total, there are 35% of 120 = 42 blue gumballs. To find the difference between the number of blue and yellow gumballs, we subtract the number of yellow gumballs (5% of 120 = 6) from the number of blue gumballs: 42 - 6 = 36. Therefore, the correct answer is D: 36. Summary: A: 48 - Incorrect. This is not the correct difference between blue and yellow gumballs. B: 30 - Incorrect. This is not the correct difference between blue and yellow gumballs. C: 42 - Incorrect. This is the total number of blue gumb

Correct Answer: D

Rationale: To find the correct amount of vanilla in mL, first, multiply 5.5 (teaspoons) by 4.93 (mL per teaspoon) to get 27.115 mL. Then round to the nearest whole number, giving 27 mL. Therefore, choice D is correct. Choices A, B, and C are incorrect as they do not result from the correct conversion calculation.

Correct Answer: A

Rationale: The correct answer is A because a quotient is the result of dividing two numbers. When you divide one number by another, the answer you get is called the quotient. For example, when you divide 10 by 2, the quotient is 5. Choice B is incorrect because the result of multiplying two numbers is called a product, not a quotient. Choice C is incorrect because the number left after subtraction is called a difference, not a quotient. Choice D is incorrect because the number remaining after a division is typically referred to as the remainder, not the quotient.

Correct Answer: A

Rationale: The correct answer is A because to convert pounds to kg, you need to multiply by the conversion factor of 2.2, and to convert kg to pounds, you need to divide by 2.2. This is because 1 pound is equal to 0.453592 kg, which is approximately 2.2 pounds per kg. Therefore, multiplying by 2.2 for pounds and dividing by 2.2 for kg ensures the correct conversion between the two units. Choices B, C, and D are incorrect because they do not correspond to the correct conversion factor between pounds and kg.
