ATI TEAS Math Practice Test

Correct Answer: D

Rationale: To solve the equation 2x + 4 = x - 6, we need to isolate x. Subtract x from both sides to get x + 4 = -6. Then, subtract 4 from both sides to get x = -10. The correct answer is D, x = -10. Choice A is incorrect because x is not -12. Choice B is incorrect as x is not 10. Choice C is incorrect as x is not -16.

Correct Answer: D

Rationale: To find the possible costs, we divide the total amount spent by the number of packages: $16/4 packages = $4 per package. Since Hannah spends at least $16, the cost per package must be less than or equal to $4. Therefore, the correct inequality is 16 ≤ 4p (Option D). The other choices are incorrect because they do not accurately represent the relationship between the total spending and the number of packages purchased.

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: A

Rationale: The correct answer is A: 1/2. When flipping a fair coin, there are only two possible outcomes - heads or tails. Since each outcome is equally likely, the probability of getting heads is 1 out of 2, or 1/2. Choice B (1/3), C (1/4), and D (1/5) are incorrect because they do not accurately reflect the equally likely outcomes of a coin flip. The probability of getting heads is always 1/2 when flipping a fair coin.

Correct Answer: A

Rationale: The correct answer is A: $2,500. To calculate the total monthly earnings, first determine the commission earned on sales: $5,000 * 3% = $150. Add this to the base salary of $2,000: $2,000 + $150 = $2,150. Therefore, the total monthly earnings will be $2,150.
