TEAS Exam Math Practice Questions
Question 1 of 5
What is the result of (6.4)(2.8) · 0.4? Which of the following is correct?
Correct Answer: D
Rationale:
To simplify the expression, first multiply 6.4 by 2.8 to get 17.92.
Then, divide the result by 0.4 to find the final answer.
Therefore, (6.4)(2.8) · 0.4 equals 44.8.
Choices A, B, and C are incorrect because they do not represent the correct result of the given expression.
Question 2 of 5
Which of the following is the y-intercept of the line whose equation is 7y − 42x + 7 = 0?
Correct Answer: C
Rationale:
To find the y-intercept, set x = 0 in the equation 7y − 42x + 7 = 0. This simplifies to 7y - 42(0) + 7 = 0, which gives 7y = -7. Solving for y, we get y = -1.
Therefore, the y-intercept is where x = 0, so the correct answer is (0, -1).
Choice A (1/6, 0) is incorrect as it does not satisfy the given equation when x = 0.
Choice B (6, 0) is incorrect as it represents the x-intercept.
Choice D (-1, 0) is incorrect as it does not correspond to the y-intercept of the given equation.
Question 3 of 5
The owner of a newspaper has noticed that print subscriptions have gone down 40% while online subscriptions have gone up 60%. Print subscriptions once accounted for 70% of the newspaper's business, and online subscriptions accounted for 25%. What is the overall percentage growth or decline in business?
Correct Answer: A
Rationale:
To calculate the decline in business, start with the 40% decline in the 70% share of print subscriptions: 40% of 70% = 0.40 0.70 = 0.28 = 28% decline. Next, calculate the growth from the 60% increase in the 25% share of online subscriptions: 60% of 25% = 0.60 0.25 = 0.15 = 15% growth.
To find the overall change, sum the decline and growth percentages: 28% decline + 15% growth = -0.28 + 0.15 = -0.13 = 13% decline.
Therefore, the overall percentage change in the newspaper's business is a 13% decline. Option A is the correct answer. Option B is incorrect because it doesn't consider the correct calculations for both the decline and growth. Option C is incorrect as it misinterprets the net change in business. Option D is incorrect as it miscalculates the overall percentage growth or decline.
Question 4 of 5
Which of the following lists is in order from least to greatest? (1/7), 0.125, (6/9), 0.60
Correct Answer: C
Rationale:
To determine the order from least to greatest, convert all fractions to decimals and compare them. Converting the fractions: (1/7) ≈ 0.14, (6/9) ≈ 0.67. The decimals in order from least to greatest are: 0.125 < 0.14 < 0.60 < 0.67.
Therefore, the correct order is 0.125, (1/7), 0.60, 6/9, making choice C the correct answer.
Choice A is incorrect as it lists (1/7) before 0.125.
Choice B is incorrect as it places 0.60 before (6/9).
Choice D is incorrect as it lists (6/9) before 0.60.
Question 5 of 5
Simplify the expression. Which of the following is the value of x? (5(4x - 5) = (3/2)(2x - 6))
Correct Answer: C
Rationale:
To solve the given proportion 5(4x - 5) = (3/2)(2x - 6), first distribute to get 20x - 25 = 3x - 9.
Then, simplify the linear equation by isolating x: 20x - 3x = 25 - 9, which leads to 17x = 16. Finally, solving for x gives x = 16/17.
Choice A is incorrect as it does not match the calculated value of x.
Choice B is incorrect as it does not correspond to the correct solution for x.
Choice D is incorrect as it does not align with the accurate value of x obtained from solving the equation.
