TEAS Practice Math Test

Correct Answer: A

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: D

Rationale: To solve for x, we add 7 to both sides of the equation: 2x - 7 + 7 = 3 + 7. This simplifies to 2x = 10. Then, we divide both sides by 2 to solve for x: 2x/2 = 10/2, which gives x = 5. Therefore, the correct answer is D. Choice A is incorrect because 4 does not satisfy the equation. Choice B is incorrect as x = 3 does not make the equation true. Choice C is incorrect as x = -2 does not satisfy the equation either.

Correct Answer: C

Rationale: To find the number of hairs used for the drug test, we need to calculate 1/7 of 100 hairs. 1/7 * 100 = 100/7 ≈ 14.29 hairs were used for the drug test. Therefore, the correct answer is C (14.29). Option A (14) is incorrect as it does not accurately represent 1/7 of 100. Option B (14.2) is also incorrect as it is not the exact result of the calculation. Option D (14.3) is incorrect as it rounds up the result, which is not necessary based on the question's requirement to round to the nearest hundredth.

Correct Answer: C

Rationale: To convert meters to centimeters, we know that 1 meter is equal to 100 centimeters. So, to find how many centimeters are in 7 meters, we multiply 7 by 100, which equals 700 centimeters. Therefore, the correct answer is C. Choice A is incorrect because it doesn't account for the conversion factor between meters and centimeters. Choice B is incorrect as it only considers 1 meter as 10 centimeters instead of 100. Choice D is incorrect as it overestimates the conversion, as 7 meters is not equal to 7000 centimeters.

Correct Answer: A

Rationale: The mode is the value that appears most frequently in a set of numbers. In this distribution, the number 1 appears the most times (5 times), making it the mode. Choice A is correct. Choices B, C, and D are incorrect because they do not represent the value that appears most frequently in the distribution.
