TEAS 7 Math Practice Test

Correct Answer: C

Rationale: To solve the equation 3(x + 4) = 18 for x, first distribute the 3: 3x + 12 = 18. Then, isolate x by subtracting 12 from both sides: 3x = 6. Finally, divide by 3 to find x = 2. Therefore, the correct answer is x = 6. Choice A is incorrect because x = 2, not 6. Choice B is incorrect because x = 4, not 6. Choice D is incorrect because x = 8, not 6.

Correct Answer: C

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: B

Rationale: The correct answer is B: 23%. To calculate this, we add up the percentages of the other three options (49% + 18% + 10% = 77%) and subtract it from 100% (100% - 77% = 23%). This gives us the percentage of funds donated to support construction costs. The rationale is that the sum of percentages of all options must add up to 100%. Choice A, C, and D are incorrect as they do not add up to 100% when combined, making B the correct answer.

Correct Answer: A

Rationale: To simplify the expression, you first add the numbers together: 1.034 + 0.275 = 1.309. Then, subtract 1.294 from the result: 1.309 - 1.294 = 0.015. Therefore, the correct answer is A (0.015). Choices B, C, and D are incorrect as they do not match the calculated result of 0.015.

Correct Answer: B

Rationale: The correct answer is B because it accurately describes the rate of change as the snow melting by 5 centimeters every day. This statement represents a consistent decrease in the snow level over time. Choice A is incorrect as it implies a higher rate of melting than what is described. Choice C is incorrect as it describes an increase rather than a decrease. Choice D is also incorrect as it describes an increase instead of the intended decrease in snow level. Therefore, choice B is the most accurate representation of the rate of change in this scenario.
