TEAS Test Math Questions Questions
Question 1 of 5
Simplify the expression 3x - 5x + 2.
Correct Answer: D
Rationale: To simplify the expression 3x - 5x + 2, we first combine like terms. 3x - 5x = -2x, so the expression becomes -2x + 2. Thus, the correct answer is D: -2x. Choice A is incorrect as it incorrectly combines the x terms without changing their signs. Choice B is incorrect as it only considers the x terms and ignores the constant term. Choice C is incorrect as it incorrectly combines the x terms without changing their signs.
Question 2 of 5
If a tree grows an average of 4.2 inches in a day, what is the rate of change in its height per month? Assume a month is 30 days.
Correct Answer: D
Rationale: To find the rate of change in height per month, we multiply the daily growth rate by the number of days in a month. 4.2 inches/day * 30 days = 126 inches/month. Therefore, the correct answer is D. Choice A is incorrect as it is the daily growth rate, not the monthly rate. Choice B is incorrect as it is the same as the daily growth rate, not the monthly rate. Choice C is incorrect as it is not the result of the correct calculation.
Question 3 of 5
What is the product of 2/3 and 3/4?
Correct Answer: A
Rationale: To find the product of 2/3 and 3/4, multiply the numerators (2 * 3 = 6) to get the new numerator and multiply the denominators (3 * 4 = 12) to get the new denominator. Therefore, the product is 6/12 which simplifies to 1/2. Choice A (1) is correct because 1 is the simplified form of the product. Choices B, C, and D are incorrect as they do not reflect the correct multiplication of fractions.
Question 4 of 5
A cell has a diameter of 0.1 meter, and another cell has a diameter of 0.05 meters. How many times larger is the first cell compared to the second cell?
Correct Answer: A
Rationale: To calculate how many times larger the first cell is compared to the second, we divide the diameter of the first cell by the diameter of the second cell: 0.1 / 0.05 = 2. Therefore, the correct answer is A: 2. Option B, C, and D are incorrect because they do not accurately represent the ratio between the two cell sizes based on the given diameters.
Question 5 of 5
Eric buys 5 1/2 pounds of apples each week for four weeks. How many total pounds does he buy?
Correct Answer: A
Rationale: To find the total pounds of apples Eric buys, we multiply the pounds he buys each week (5 1/2) by the number of weeks (4). 5 1/2 * 4 = 22 pounds. Thus, the correct answer is A (22 pounds). Other choices are incorrect because they do not correctly calculate the total pounds based on the given information. B, C, and D are not the correct results of multiplying 5 1/2 by 4.
