TEAS Practice Math Test

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: A

Rationale: The correct answer is A: $600. The first step is to calculate the amount saved after paying rent and utilities. Since she uses 2/5 for rent and utilities, she saves 3/5 of her monthly contribution. Then, she saves half of this amount for incidental expenditures, which means she spends the other half on medical supplies. Therefore, she spends 1/4 of her monthly contribution on medical supplies. If we let her monthly contribution be x, then 1/4 of x equals $600. Therefore, the correct answer is $600. Choices B, C, and D are incorrect because they do not align with the calculations based on the given information.

Correct Answer: D

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: 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.
