ATI TEAS 7
TEAS Exam Math Practice Questions
Question 1 of 5
4 − 1/(22) + 24 � (8 + 12). Simplify the expression. Which of the following is correct?
Correct Answer: C
Rationale: Failed to generate a rationale after 5 retries.
Question 2 of 5
Simplify the expression. Which of the following is the value of x? (5(4x - 5) = (3/2)(2x - 6))
Correct Answer: C
Rationale: To solve the equation 5(4x - 5) = (3/2)(2x - 6), first distribute on both sides to get 20x - 25 = 3x - 9. Then, move x terms to one side and constants to the other side to get 17x = 16. Finally, divide by 17 to find x = 16/17, which is the correct answer (C). The other choices are incorrect because they do not yield the correct value of x when substituted back into the original equation.
Question 3 of 5
Which of the following is the correct solution to the equation 3x + 4 = 19?
Correct Answer: C
Rationale: To solve the equation 3x + 4 = 19, we first isolate the variable x. Subtract 4 from both sides: 3x = 15 Then, divide by 3 on both sides: x = 5 Therefore, the correct answer is C: x = 5. Choice A is incorrect as 3(3) + 4 = 13, not 19. Choice B is incorrect as 3(4) + 4 = 16, not 19. Choice D is incorrect as 3(6) + 4 = 22, not 19.
Question 4 of 5
Which of the following is equivalent to 8 pounds and 8 ounces? (Round to the nearest tenth of a kilogram.)
Correct Answer: B
Rationale: To convert 8 pounds and 8 ounces to kilograms, first convert pounds to kilograms (1 lb = 0.453592 kg) and ounces to kilograms (1 oz = 0.0283495 kg). So, 8 lbs + 8 oz is approximately 3.9 kg. Therefore, choice B (3.9 kilograms) is the correct equivalent. Choice A (3.6 kg) is too low, and choices C (17.6 kg) and D (18.7 kg) are too high based on the conversion rates.
Question 5 of 5
Which statement about the following set is true? {60, 5, 18, 20, 37, 37, 11, 90, 72}
Correct Answer: D
Rationale: The correct answer is D: The median is less than the mean. To find the median, first arrange the set in ascending order {5, 11, 18, 20, 37, 37, 60, 72, 90}. The median is the middle value, which is 37 here. To find the mean, add up all numbers and divide by the total count (sum/9). The mean is (60+5+18+20+37+37+11+90+72)/9 = 41.67. Since 37 (median) is less than 41.67 (mean), the statement is true. Other choices are incorrect because A is false as median ≠mean, B is false since mean > mode, and C is false since mode ≠median.
