Correct Answer: D

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: C

Rationale: To solve the equation 5(4x - 5) = (3/2)(2x - 6), first distribute on both sides to get 20x - 25 = 3x - 9. Then, move x terms to one side and constants to the other side to get 17x = 16. Finally, divide by 17 to find x = 16/17, which is the correct answer (C). The other choices are incorrect because they do not yield the correct value of x when substituted back into the original equation.

Correct Answer: B

Rationale: The correct answer is B because when simplifying the expression 14 - 7 + (-7), we get 14 - 7 - 7 = 0, which is not a negative value. A: (-3)(-1)(2)(-1) simplifies to 6, which is a positive value. C: 7 - 10 + (-8) simplifies to -11, a negative value. D: -5(-2)(-3) simplifies to -30, a negative value. Thus, B is the only choice that results in a non-negative value.

Correct Answer: A

Rationale: To calculate the shop's revenue over three days, we need to consider the total sales of sandwiches, drinks, and cookies over the three days. The revenue formula should include the earnings from each item multiplied by the quantity sold. Therefore, the correct equation is r = 4s + 2d + 1c. This is because for each sandwich sold, the shop earns $4, for each drink $2, and for each cookie $1. Choices B, C, and D are incorrect as they incorrectly multiply the earnings by multiples of the quantities sold, which would result in an inflated revenue amount.

Correct Answer: C

Rationale: To solve the equation 3x + 4 = 19, we first isolate the variable x. Subtract 4 from both sides: 3x = 15 Then, divide by 3 on both sides: x = 5 Therefore, the correct answer is C: x = 5. Choice A is incorrect as 3(3) + 4 = 13, not 19. Choice B is incorrect as 3(4) + 4 = 16, not 19. Choice D is incorrect as 3(6) + 4 = 22, not 19.
