TEAS Practice Math Test

Correct Answer: B

Rationale: The correct answer is B: y = 3x. By examining the chart, we see that y values are three times the x values. This relationship is represented by y = 3x. Choice A (x = 3y) reverses the relationship, choice C (y = 1/3x) states that y values are one-third of x values, and choice D (x/y = 3) represents x divided by y being equal to 3, which is not consistent with the given data in the chart.

Correct Answer: B

Rationale: The median is the middle value when numbers are arranged in ascending order. In this case, when the scores 81, 92, 87, 89, and 94 are arranged in ascending order, the middle value is 89. Therefore, the correct answer is B. Choice A (87) is incorrect as it is not the middle value when arranged in ascending order. Choices C (92) and D (94) are also incorrect as they are not the middle values when the numbers are arranged in ascending order.

Correct Answer: A

Rationale: The correct answer is A: x + 4 = (1/3)y - 2. To break down the equation: 1. "Four more than a number, x" can be represented as x + 4. 2. "2 less than 1/3 of another number, y" can be represented as (1/3)y - 2. 3. Combining the two expressions gives x + 4 = (1/3)y - 2, which correctly represents the given sentence. Other choices are incorrect because they do not accurately capture the relationship between x and y as described in the sentence. Choice B incorrectly sets 4x equal to 2 minus 1/3 of y, while choices C and D have incorrect signs and placements of terms.

Correct Answer: B

Rationale: The correct answer is B: b = 5w + 10. To determine the correct equation, we can analyze the data in the table given. We can observe that when the number of weeks increases by 1, the number of books checked out increases by 5. This indicates a constant rate of increase of 5 books per week, which aligns with the equation b = 5w + 10. The initial value of 10 represents the number of books already checked out before week 1. Choices A, C, and D do not exhibit a constant rate of increase or the correct initial value based on the data provided.

Correct Answer: C

Rationale: To calculate the total square inches of wrapping paper needed, we first find the surface area of the box. The surface area of a rectangular box is calculated by adding the areas of all its faces. For this box, the surface area is 2(14x8) + 2(14x6) + 2(8x6) = 224 + 168 + 96 = 488 square inches. Therefore, the correct answer is C (488). Choice A (56) is incorrect because it is too small and does not account for all sides of the box. Choice B (244) is also incorrect as it is not the total surface area of the box. Choice D (672) is incorrect as it is too large and does not accurately represent the wrapping paper needed.
