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: To calculate the total cost, first multiply the daily rental cost by the number of days ($50 * 3 = $150). Then, multiply the cost per mile by the total miles driven ($0.25 * 120 = $30). Add these two amounts ($150 + $30 = $180). Therefore, the correct total cost is $180. Among the choices, only option A ($156) is incorrect as it does not match the calculated total cost. Option B ($190) is incorrect as it is higher than the correct total cost. Option C ($165) is incorrect as it is also higher than the correct total cost. Option D ($210) is incorrect as it is higher than the correct total cost.

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.
