ATI TEAS Math Practice Test

Correct Answer: A

Rationale: To simplify the expression, we first multiply: (3)(-4) = -12, (3)(4) = 12. Substitute these values back into the expression: -12 + 12 - 1 = -1. Therefore, the correct answer is A (-1). Choices B, C, and D are incorrect as they do not match the calculated result of -1.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. The total cost is directly proportional to the number of hours rented. 2. The cost per hour is $3.60, so multiplying the number of hours (h) by the cost per hour will give the total cost. 3. Therefore, the equation C = 3.60h correctly represents this relationship. Summary: B: Incorrect, as it incorrectly adds the number of hours to the cost per hour. C: Incorrect, as it unnecessarily adds a fixed cost of $10.80 to the total cost equation. D: Incorrect, as it incorrectly assumes a fixed cost per hour of $10.80.

Correct Answer: C

Rationale: To find the final dosage, we first reduce 310 mg by 1/5, which is 310 * (1 - 1/5) = 248 mg. Then, we further reduce it by 20 mg, resulting in 248 - 20 = 228 mg. Therefore, the patient's final dosage is 228 mg. Option A (20 mg) is incorrect because it only accounts for the second reduction. Option B (42 mg) is incorrect as it doesn't consider both reductions. Option D (248 mg) is incorrect as it doesn't factor in the second reduction.

Correct Answer: B

Rationale: To simplify the expression 13 - 3/22 - 11, we first calculate 3/22 which is 0.136. Then, we subtract 0.136 from 13, resulting in 12.864. Lastly, we subtract 11 from 12.864, giving us 1.864. Therefore, the correct answer is B: 7/22. Choices A, C, and D are incorrect as they do not match the simplified expression value of 1.864.

Correct Answer: A

Rationale: To solve for x, first isolate x by subtracting 6 from both sides: 2x + 6 - 6 = 14 - 6. This simplifies to 2x = 8. Then, divide both sides by 2 to solve for x: 2x/2 = 8/2, which gives x = 4. This is the correct answer as it accurately solves the equation. Choice B, x=8, is incorrect as it does not satisfy the equation. Choice C, x=10, and choice D, x=13, are also incorrect as they do not align with the correct solution derived from the steps provided.
