TEAS 7 Math Practice Test Questions
Question 1 of 5
Simplify the following expression: 4 * (2/3) · 1 * (1/6)
Correct Answer: C
Rationale:
To simplify the expression, first convert the mixed numbers into fractions: 4 * (2/3) · 1 * (1/6). This becomes 4 * 2/3 · 1 * 1/6. Next, perform the multiplication and division from left to right: 8/3 · 1 * 1/6 = 8/3 * 1 * 6 = 8/3 * 6 = 16.
Therefore, the correct answer is 4.
Choice A (2) is incorrect as it does not represent the final simplified expression.
Choice B (3 1/3) is incorrect as it does not match the result of simplifying the expression.
Choice D (4 1/2) is incorrect as it does not match the result of simplifying the expression.
Question 2 of 5
In a study where 60% of respondents use smartphones to check their email, and 5,000 respondents were included, how many respondents use smartphones for email?
Correct Answer: A
Rationale: In the study, 60% of 5,000 respondents using smartphones for email would equal 3,000 respondents, not the total number of respondents.
Therefore, the correct answer is 3,000 respondents.
Choice B, 2,500 respondents, is incorrect because it doesn't consider the percentage of smartphone users.
Choice C, 5,000 respondents, is incorrect as it represents the total number of respondents, not the specific number using smartphones for email.
Choice D, 1,000 respondents, is incorrect as it is not the correct calculation based on the given information.
Question 3 of 5
Mandy can buy 4 containers of yogurt and 3 boxes of crackers for $9.55. She can buy 2 containers of yogurt and 2 boxes of crackers for $5.90. How much does one box of crackers cost?
Correct Answer: C
Rationale:
To solve this problem, we can set up a system of equations. Let the cost of one container of yogurt be y and the cost of one box of crackers be c. From the first scenario, we have 4y + 3c = 9.55. From the second scenario, we have 2y + 2c = 5.90. Solving these equations simultaneously, we find that c = $2.25.
Therefore, one box of crackers costs $2.25.
Choice A, $1.75, is incorrect because it does not satisfy the given conditions in the system of equations.
Choice B, $2.00, is incorrect as it does not match the calculated solution.
Choice D, $2.50, is incorrect as it does not align with the calculated value for one box of crackers.
Question 4 of 5
Solve for x: 3(x + 4) = 18
Correct Answer: C
Rationale:
To solve the equation 3(x + 4) = 18, first distribute the 3 to both terms inside the parentheses: 3x + 12 = 18. Next, isolate the variable x by subtracting 12 from both sides: 3x = 6. Finally, divide by 3 to solve for x, giving x = 6.
Choice A, x = 2, is incorrect as the correct solution is x = 6.
Choices B (x = 4) and D (x = 8) are also incorrect as they do not satisfy the given equation.
Question 5 of 5
Which statement best describes the rate of change?
Correct Answer: B
Rationale: The rate of change refers to how one quantity changes concerning another quantity. In this scenario, the rate of change is the amount of snow melting per day, which is 5 centimeters. This is determined by the slope of the graph, indicating a decrease in snow depth.
Choices C and D incorrectly describe an increase in snow depth, while choice A exaggerates the rate of snow melting compared to the actual value of 5 centimeters per day.
