TEAS Exam Math Practice

Correct Answer: A

Rationale: To find the diameter of a circle from its circumference, we use the formula: Diameter = Circumference / π. Given the circumference is 49 feet, we can calculate the diameter by dividing 49 by π (approximately 3.14), resulting in 15.6 feet, which is choice A. Option B, 17.8 feet, is incorrect as it does not match the calculation. Option C, 49 feet, is the circumference, not the diameter. Option D, 153.9 feet, is incorrect as it is not the result of dividing the circumference by π. Therefore, choice A is the correct answer based on the formula for finding the diameter of a circle.

Correct Answer: D

Correct Answer: D

Rationale: To solve the expression, we follow the order of operations (PEMDAS). First, we evaluate the parentheses: 3 - 4 = -1. Then, we multiply 7 by -1 to get -7. Next, we subtract -7 from 102 to get 109. Finally, subtract 25 from 109 to get the correct answer of 84 (D). Choices A, B, and C are incorrect because they do not follow the correct order of operations or make calculation errors.

Correct Answer: D

Rationale: To solve the equation 8x - 6 = 3x + 24, first, simplify both sides. Subtract 3x from both sides to get 5x - 6 = 24. Then, add 6 to both sides to get 5x = 30. Finally, divide by 5 to find x = 6. This is the correct solution as it satisfies the original equation. Choice A, B, and C are incorrect as they do not result in a true statement when substituted back into the equation.
