TEAS Exam Math Practice

Correct Answer: B

Rationale: The correct answer is B because when simplifying the expression 14 - 7 + (-7), we get 14 - 7 - 7 = 0, which is not a negative value. A: (-3)(-1)(2)(-1) simplifies to 6, which is a positive value. C: 7 - 10 + (-8) simplifies to -11, a negative value. D: -5(-2)(-3) simplifies to -30, a negative value. Thus, B is the only choice that results in a non-negative value.

Correct Answer: C

Rationale: To calculate the total cost: 1. Convert all weights to kilograms: - Apples: 1.2 kg - Bananas: 0.8 kg - Strawberries: 0.3 kg 2. Calculate the total weight: 1.2 + 0.8 + 0.3 = 2.3 kg 3. Multiply total weight by the flat rate: 2.3 kg x $4/kg = $9.20 Therefore, the correct answer is C: $9.20. Other choices are incorrect because they do not follow the correct calculation based on the flat rate per kilogram.

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.

Correct Answer: D

Rationale: The total bill includes the original cost of dinner and the tip. To find the tip amount, we calculate 20% of $48.30, which is $9.66. Adding this to the original bill gives $48.30 + $9.66 = $57.96. Therefore, the correct answer is D. Option A is incorrect as it only represents the tip amount. Option B is incorrect as it is the original bill amount without the tip. Option C is incorrect as it is the same as the original bill without the tip.
