TEAS Test Math Questions Questions
Question 1 of 5
What is the median of the data set: 3, 5, 7, 9, 11?
Correct Answer: B
Rationale:
To find the median of a set of numbers, you arrange them in ascending order and then find the middle value. Given the data set 3, 5, 7, 9, 11, when arranged in ascending order, becomes 3, 5, 7, 9, 11. The middle value in this set is 7, making it the median.
Choice A (3) is the smallest value, not the middle value.
Choice C (9) and
Choice D (5) are not the middle values of the set either.
Therefore, the correct answer is B (7).
Question 2 of 5
Simplify the expression: 2x + 3x - 5.
Correct Answer: A
Rationale:
To simplify the expression 2x + 3x - 5, follow these steps: Identify and combine like terms. The terms 2x and 3x are both 'like terms' because they both contain the variable x. Add the coefficients of the like terms: 2x + 3x = 5x. Simplify the expression. After combining the like terms, the expression becomes 5x - 5, which includes the simplified term 5x and the constant -5. Thus, the fully simplified expression is 5x - 5, making Option A the correct answer. This method ensures all terms are correctly simplified by combining similar elements and retaining constants.
Question 3 of 5
Which proportion yields a different number for the unknown compared to the others?
Correct Answer: D
Rationale:
To find the value of x in each proportion, cross multiply. For proportion A, x = 4; for B, x = 8; for C, x = 6; and for D, x = 10. Hence, proportion D yields a different value for x compared to the others.
Choices A, B, and C all result in unique values for x, but these values are distinct from the value obtained in proportion D.
Question 4 of 5
Solve for x in the equation: 3x - 5 = 16
Correct Answer: C
Rationale:
To solve for x, add 5 to both sides of the equation: 3x - 5 + 5 = 16 + 5, which simplifies to 3x = 21. Next, divide both sides by 3: x = 21 · 3 = 7.
Therefore, the correct answer is x = 7, making option A the correct choice. Option C, '8,' is incorrect as it is not the solution obtained from the correct calculations. Options B and D, '5' and '9,' are also incorrect and not the solution to the given equation.
Question 5 of 5
Evaluate the expression -3 x 5.
Correct Answer: A
Rationale: The correct answer is A, which is -15. When you multiply -3 by 5, you get -15. The negative sign in front of the 3 indicates a negative value, and when multiplied by a positive number like 5, the result remains negative.
Choices B, C, and D are incorrect because they do not reflect the correct multiplication of -3 and 5.
