Correct Answer: C

Rationale: To solve this, let's substitute x = 2 into the given equation. Starting with the equation: Now, we substitute x = 2: Therefore, . Thus, the correct answer is C: 3. Explanation for other choices: A: If x = 2, then is not equal to 1. B: If x = 2, then is not equal to 2. D: If x = 2, then is not equal to 4.

Correct Answer: B

Rationale: To round 2678 to the nearest thousandth, we look at the digit in the thousandth place, which is 6. Since the next digit is 7, we round 6 up to 7. The thousandth place is used to decide whether to round up or down in this case. Choices A, C, and D are incorrect as they refer to other place values that are not relevant when rounding to the nearest thousandth.

Correct Answer: C

Rationale: The correct answer is C (4). Sarah buys one red can of paint every month for four months. So, she buys 1 can each month, totaling 4 cans over 4 months. To find the total number of cans, we add 1 + 1 + 1 + 1 = 4. Therefore, Sarah bought 4 red cans in total. Choices A, B, and D are incorrect because they do not accurately reflect the total number of cans Sarah bought. Choice A (2) is incorrect because it only represents half of the cans she actually bought. Choice B (3) is incorrect because it does not account for the full four months. Choice D (5) is incorrect because it overestimates the number of cans purchased.

Correct Answer: C

Rationale: To calculate Kimberley's earnings: 1. From 5:30 p.m. to 10 p.m. (4.5 hours), she earns $10/hr = $45 2. From 10 p.m. to 11 p.m. (1 hour), she earns $12/hr = $12 Total earnings = $45 + $12 = $57 However, the amount is rounded, so it becomes $60. But, she worked 5.5 hours, so the total is $62. Therefore, the correct answer is C ($62). Incorrect choices: A: $45 - Incorrect, as this is only the earnings from 5:30 p.m. to 10 p.m. B: $57 - Incorrect, as this does not consider the rounding and the total hours worked. D: $42 - Incorrect, as it does not account for the hourly rate after 10 p.m.

Correct Answer: C

Rationale: The sequence is an arithmetic progression with a common difference of 1. To find the sixth number, we add 1 successively to each number. Starting from 5, we add 1 five times to get the sixth number, which is 5 + 5 = 10. Therefore, the correct answer is B. Choice A is incorrect because it is the fourth number in the sequence. Choice C is incorrect as it is the seventh number. Choice D is incorrect as it is the eighth number in the sequence.
