TEAS Test Math Questions Questions
Question 1 of 5
Simplify the expression: 2x + 3x - 5.
Correct Answer: A
Rationale: To simplify the expression 2x + 3x - 5, we combine like terms. First, add 2x and 3x to get 5x. Then, subtract 5 from 5x to get the final simplified expression: 5x - 5. Therefore, choice A is correct. Choices B, C, and D are incorrect because they do not correctly combine the like terms or subtract the constant term from the final result.
Question 2 of 5
What is the mean for the data set 16, 18, 17, 15, 19, 14, 12, 11, 10, 16, 18, and 17?
Correct Answer: C
Rationale: To find the mean, sum all values and divide by the total count. For this data set, sum = 16+18+17+15+19+14+12+11+10+16+18+17 = 183. Total count = 12. Mean = 183/12 = 15.25, which makes choice C, 16, the correct answer. Choice A, 14.25, and B, 15.25, are incorrect as they do not match the calculated mean. Choice D, 17, is incorrect as it is higher than the calculated mean value.
Question 3 of 5
Solve the equation for the unknown. 3x + 2 = 20
Correct Answer: C
Rationale: To solve 3x + 2 = 20, first subtract 2 from both sides to isolate 3x. This gives 3x = 18. Then divide by 3 to solve for x, yielding x = 6. Choice C is correct because 3(6) + 2 equals 20. Choices A, B, and D are incorrect because they do not satisfy the original equation when substituted back in.
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
Write 290% as a fraction.
Correct Answer: D
Rationale: To convert a percentage to a fraction, we divide the percentage by 100. So, 290% is equal to 290/100. Simplifying this fraction gives us 29/10. Therefore, the correct answer is D. Option A (29/10) is the simplified form of the correct answer. Option B (58/20) and Option C (145/50) are incorrect as they are not equivalent to 290%.
