TEAS Exam Math Practice

Correct Answer: D

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: C

Rationale: To find the y-intercept, set x=0 in the equation 7y - 42x + 7 = 0: 7y - 42(0) + 7 = 0 7y + 7 = 0 7y = -7 y = -1 Thus, the y-intercept is (0, -1). Summary: A: Incorrect - The x-coordinate is not 1/6. B: Incorrect - The x-coordinate is not 6. C: Correct - The y-intercept is (0, -1). D: Incorrect - The x-coordinate is not -1.

Correct Answer: B

Rationale: To simplify the expression, we follow the order of operations (PEMDAS). First, we calculate the exponents: 52(3) + 3(-2)^2 / 4 + 9 - 2(5-8) = 156 + 3(4) / 4 + 9 - 2(3) = 156 + 12 / 4 + 9 - 6. Then, we perform division and multiplication from left to right: 156 + 3 + 9 - 6 = 168. Therefore, the correct answer is 87/19. Choices A, C, and D are incorrect as they do not correctly simplify the expression following the order of operations.

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: A

Rationale: To find the sale price after a 20% discount, we first calculate the discount amount: 20% of $30 is $6. Subtracting this discount from the original price gives us the sale price: $30 - $6 = $24, which is choice A. Other choices are incorrect as they do not reflect the correct calculation of the discount. B, C, and D are all higher than the correct answer, indicating incorrect calculations.
