Math HESI A2 Practice Test

Correct Answer: A

Rationale: To convert ounces to pounds, we divide by 16 (since 1 pound = 16 ounces). Therefore, 48 ounces ÷ 16 = 3 pounds. So, the correct answer is A: 3 lbs. Choice B, 6 lbs, is incorrect as it would be 48 ounces ÷ 8 (not 16). Choice C, 4 lbs, and choice D, 8 lbs, are also incorrect based on the conversion factor of 1 pound = 16 ounces.

Correct Answer: B

Rationale: To solve for x in the equation 4x + 2 = 18, we first isolate x by subtracting 2 from both sides, giving us 4x = 16. Then, we divide both sides by 4 to find x = 4, which is choice B. The correct answer is x = 4 because substituting x = 4 back into the original equation gives 4(4) + 2 = 18, which simplifies to 16 + 2 = 18, confirming that x = 4 is the solution. Choices A, C, and D are incorrect because they do not satisfy the original equation when substituted back in.

Correct Answer: D

Rationale: To find 50% of 120, you multiply 120 by 0.50 (which represents 50%). So, 120 x 0.50 = 60. Therefore, the correct answer is D. Choice A (50) is incorrect because it represents the percentage value, not the result of the calculation. Choice B (50) is a duplicate of Choice A. Choice C (70) is incorrect as it is not the result of finding 50% of 120.

Correct Answer: C

Rationale: To solve for x, add 7 to both sides of the equation: 2x - 7 + 7 = 9 + 7. This simplifies to 2x = 16. Then, divide by 2 on both sides to get x = 8. This is the correct answer (C) because it correctly follows the principles of algebra. Choices A, B, and D are incorrect as they do not yield the correct solution when substituted back into the original equation.

Correct Answer: A

Rationale: To find the result of subtracting 4.7 from 9.5, we need to subtract 4.7 from 9.5. This can be calculated as 9.5 - 4.7 = 4.8. Therefore, the correct answer is A. Choice B (4.9) is incorrect because it is not the result of the subtraction operation provided in the question. Choice C (4.6) is incorrect because it is the result of subtracting 5.1 from 9.7, not 4.7 from 9.5. Choice D (4.7) is incorrect because it is the number being subtracted and not the final result of the subtraction.
