TEAS 7 Math Practice Test

ATI TEAS 7

1. Simplify the following expression: 7 + 16 - (5 + 6 × 3) - 10 × 2

A. -42
B. -20
C. 23
D. 20

Correct answer: B

Rationale: Start by solving the multiplication and parentheses. The answer is -20.

2. A can has a radius of 1.5 inches and a height of 3 inches. Which of the following best represents the volume of the can?

A. 17.2 in³
B. 19.4 in³
C. 21.2 in³
D. 23.4 in³

Correct answer: C

Rationale: The volume of a cylinder is calculated using the formula V = πr²h, where r is the radius and h is the height. Substituting the given values (r = 1.5 inches, h = 3 inches) into the formula yields V ≈ 21.2 in³. Therefore, the correct answer is C. Choice A, 17.2 in³, is incorrect as it does not correspond to the correct calculation. Choice B, 19.4 in³, is also incorrect and does not match the calculated volume. Choice D, 23.4 in³, is not the correct volume obtained when using the provided dimensions in the formula for the volume of a cylinder.

3. Solve for x: 3(x + 4) = 18

A. x = 2
B. x = 4
C. x = 6
D. x = 8

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.

4. Two even integers and one odd integer are multiplied together. Which of the following could be their product?

A. 3.75
B. 9
C. 16.2
D. 24

Correct answer: D

Rationale: When multiplying two even integers and one odd integer, the product will always be even. This is because multiplying any number of even integers will always result in an even number. Therefore, the only possible product from the given options is 24, as it is the only even number listed. Choices A, B, and C are incorrect as they are all odd numbers, and the product of two even integers and one odd integer will never result in an odd number.

5. Simplify the following expression: 4 * (2/3) ÷ 1 * (1/6)

A. 2
B. 3 1/3
C. 4
D. 4 1/2

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.
