Practice Math TEAS TEST

Correct Answer: A

Rationale: To solve for x in the equation (x/y) - z = rw, we first isolate x by multiplying both sides by y to get x - yz = rwy. Then, we add yz to both sides to get x = rwy + yz, which simplifies to x = y(rw + z). Therefore, the correct answer is A: x = y(z + rw). Choice B is incorrect as it incorrectly distributes the y term. Choice C is incorrect as it incorrectly combines the terms. Choice D is incorrect as it incorrectly subtracts z instead of adding it.

Correct Answer: A

Rationale: The correct answer is A: 1000 mL. This is because there are 1000 milliliters in a liter based on the metric system conversion. 1 liter is equal to 1000 milliliters. Therefore, to convert liters to milliliters, you simply multiply the number of liters by 1000. Choice B: 100 mL is incorrect because it is not the standard conversion factor for liters to milliliters. Choice C: 10 mL is incorrect as it is too small of a quantity to be equivalent to a liter. Choice D: 1 mL is incorrect as it is significantly less than a liter.

Correct Answer: D

Rationale: The correct answer is D: No correlation. This is because the scatter plot does not show a clear pattern or trend between exam scores and heights. There is no apparent increase or decrease in one variable as the other variable changes. It indicates that there is no relationship between the two variables. Choice A (Positive) is incorrect because there is no consistent upward trend in the data points. Choice B (Positive and Negative) is incorrect as there is no presence of both positive and negative correlations simultaneously. Choice C (Negative) is incorrect since there is no consistent downward trend in the data points. The absence of any clear trend or pattern indicates a lack of correlation, making choice D the correct answer.

Correct Answer: A

Rationale: The correct answer is A because a prime number is defined as a number that is divisible by only 1 and itself. This means prime numbers have exactly two factors, 1 and the number itself, making them indivisible by any other number. Choice B is incorrect because prime numbers are not divisible by any other numbers except 1 and themselves. Choice C is incorrect because prime numbers are not divisible by any number, only by 1 and themselves. Choice D is incorrect because prime numbers actually have exactly two factors, not three.

Correct Answer: D

Rationale: Step 1: Let x be the original price of the recliner. Step 2: Sale price = x - 0.3x = 0.7x Step 3: Price after coupon = 0.7x - 0.25(0.7x) = 0.525x Step 4: Set up equation: 0.525x = 237 Step 5: Solve for x: x = 237 / 0.525 ≈ $451 Step 6: The original price is closest to $451, making option C incorrect. Step 7: Check why other choices are incorrect: - Option A: $316 is too low for the original price. - Option B: $431 is the calculated sale price, not the original price. - Option D: $527 is the original price based on the calculation.
