Math Practice TEAS Test

Correct Answer: A

Rationale: The correct answer is A: x + 4 = 5/6y - 2. To break it down step-by-step: 1. "Four more than a number" translates to x + 4. 2. "2 less than 5/6 of another number" translates to 5/6y - 2. 3. Combining the two expressions gives x + 4 = 5/6y - 2, which represents the given relationship accurately. In summary, choice A is correct because it correctly captures the relationship described in the question. Choices B, C, and D are incorrect because they do not accurately represent the relationship between the two numbers given in the question.

Correct Answer: B

Rationale: To solve the equation, we follow the order of operations: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Step 1: 5 + 3 = 8 Step 2: 4 - 6 = -2 Step 3: -2 / 2 = -1 Step 4: 8 - 1 = 7 Therefore, the correct answer is 7 (Option D). Option A is incorrect as it does not consider all operations. Option C is incorrect as it does not correctly follow the order of operations. Option D is incorrect as it does not correctly calculate the result.

Correct Answer: A

Rationale: To find the percentage of students with hazel or green eyes, add the number of students with hazel and green eyes (5+2=7). Then, divide this sum by the total number of students (7/30). Finally, multiply the result by 100 to convert it to a percentage (7/30 * 100 = 23%). Therefore, the correct answer is A (0.23). Choice B (0.3) is incorrect as it is not the accurate percentage of students with hazel or green eyes. Choice C (0.47) and choice D (0.77) are also incorrect as they do not represent the correct calculation of the percentage based on the given information.

Correct Answer: A

Rationale: The correct answer is A: x + 4 = 5/6y - 2. To break it down step-by-step: 1. "Four more than a number" translates to x + 4. 2. "2 less than 5/6 of another number" translates to 5/6y - 2. 3. Combining the two expressions gives x + 4 = 5/6y - 2, which represents the given relationship accurately. In summary, choice A is correct because it correctly captures the relationship described in the question. Choices B, C, and D are incorrect because they do not accurately represent the relationship between the two numbers given in the question.

Correct Answer: B

Rationale: The correct answer is B: 16 ounces. There are 16 ounces in a pound because this is the standard conversion rate between ounces and pounds. To arrive at this conversion, we can use the fact that 1 pound is equal to 16 ounces. Therefore, if you have 1 pound and you want to convert it to ounces, you would multiply 1 pound by 16 ounces/pound, which gives you 16 ounces. Summary of other choices: A: 8 ounces - This is incorrect because 8 ounces is half of a pound, not the full conversion rate. C: 32 ounces - This is incorrect because 32 ounces is actually equivalent to 2 pounds, not 1 pound. D: 12 ounces - This is incorrect as it is not the standard conversion rate between ounces and pounds.
