Correct Answer: B

Rationale: To simplify the expression 3(1/6) - 1(5/6), we first multiply the whole number by the fraction: 3 * 1/6 = 3/6. Then, we subtract 1 * 5/6 = 5/6. Simplifying 3/6 - 5/6 gives us -2/6, which reduces to -1/3 or 1 (1/3). Therefore, the correct answer is B: 1 (1/3). Choice A: 2 (1/3) is incorrect as the result is negative. Choice C: 2 (1/9) is incorrect as it is not the simplified form. Choice D: 5/6 is incorrect as it is one of the terms in the expression, not the final result.

Correct Answer: C

Rationale: To find the number of data analysis problems, first, determine the total ratio parts: 4 + 2 = 6. Then, calculate the number of parts for algebra problems: 2/6 * 18 = 6. Finally, find the number of data analysis problems: 4/6 * 18 = 12. Therefore, the correct answer is C (36). Option A (24) is incorrect as it miscalculates the ratio. Option B (28) and Option D (38) do not consider the given ratio and total number of algebra problems.

Correct Answer: A

Rationale: To convert 56 kilograms to pounds, we use the conversion factor that 1 kilogram is approximately 2.2 pounds. So, 56 kg x 2.2 = 123.2 pounds. Since we are asked for the approximate weight in pounds, we round it to the nearest whole number, which is 123 pounds. Summary: - A (123 pounds) is correct because it is the accurate conversion of 56 kilograms to pounds. - B (110 pounds), C (156 pounds), and D (137 pounds) are incorrect as they do not correctly convert 56 kilograms to pounds using the conversion factor.

Correct Answer: C

Rationale: To convert kilometers to miles, we can use the conversion factor of 1 kilometer is approximately 0.621 miles. Therefore, to find the distance in miles, we multiply 45 kilometers by 0.621, which equals approximately 28 miles. Choice C is correct because it correctly converts the distance from kilometers to miles. Choice A (42 miles), Choice B (37 miles), and Choice D (16 miles) are incorrect because they do not correctly convert kilometers to miles. Choice A overestimates the distance, Choice B underestimates it, and Choice D significantly underestimates it.

Correct Answer: A

Rationale: To solve for x, first isolate x by subtracting 6 from both sides: 2x + 6 - 6 = 14 - 6. This simplifies to 2x = 8. Then, divide both sides by 2 to solve for x: 2x/2 = 8/2, which gives x = 4. This is the correct answer as it accurately solves the equation. Choice B, x=8, is incorrect as it does not satisfy the equation. Choice C, x=10, and choice D, x=13, are also incorrect as they do not align with the correct solution derived from the steps provided.
