TEAS Math Practice Test

Correct Answer: A

Rationale: To solve for y, first isolate y by adding 7 to both sides of the equation: 5y - 7 + 7 = 13 + 7. This simplifies to 5y = 20. Then, divide by 5 on both sides to find y = 4. Thus, the correct answer is A: 4. Choices B, C, and D are incorrect as they do not satisfy the equation 5y - 7 = 13.

Correct Answer: A

Rationale: To find what number is 6 equal to 30% of, we set up the equation: 0.30x = 6. Solving for x, we get x = 6 / 0.30 = 20. Therefore, 6 is equal to 30% of 20. Choice A (18) is incorrect because 30% of 18 is 5.4, not 6. Choices B, C, and D are also incorrect as their respective calculations do not result in 6.

Correct Answer: C

Rationale: The number -4 is classified as real, rational, and integer. 1. Real: -4 is a real number as it exists on the number line. 2. Rational: -4 can be expressed as -4/1, which is a ratio of two integers. 3. Integer: -4 is a whole number that includes negative numbers. Therefore, the correct answer is C. Summary: A: Incorrect, as it includes "natural," which does not apply to negative numbers. B: Incorrect, as it includes "natural," which is only positive integers. D: Incorrect, as -4 is rational, not irrational.

Correct Answer: B

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: A

Rationale: The mode is the number that appears most frequently in a set. In this case, the number 4 appears twice, which is more frequent than any other number in the set. Therefore, the mode of {4, 4, 5, 7, 8} is 4. Choice B (5), C (7), and D (8) are incorrect because each of these numbers appears only once in the set, making them less frequent than 4. The mode must be the number that appears most often in the set, which is 4.
