Practice Math TEAS TEST

Correct Answer: A

Rationale: To find the sum of three times a number and eight times a different number, we need to add 3 times the first number (3x) to 8 times the second number (8y). Therefore, the correct expression is 3x + 8y (Choice A). This choice correctly represents the operation of adding the terms. Choices B, C, and D either incorrectly combine the coefficients of x and y or use subtraction instead of addition, making them incorrect for this question.

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.

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: C

Rationale: To convert 45 kg to pounds, multiply by the conversion factor 2.2 lbs/kg. So, 45 kg * 2.2 lbs/kg = 99 lbs. Therefore, the correct answer is C. Choice A (120 lbs) is incorrect as it is not the result of the conversion calculation. Choice B (89 lbs) is also incorrect as it does not match the conversion result. Choice D (90 lbs) is incorrect because the correct equivalent weight is 99 lbs, not 90 lbs.

Correct Answer: B

Rationale: To find the sale price of the sweater marked 15% off, you first calculate the discount amount by multiplying $78 by 15% (0.15), which equals $11.70. Then deduct this discount from the original price: $78 - $11.70 = $66. Therefore, choice B ($66) correctly estimates the sale price. Choice A ($12) is too low and does not consider the 15% discount. Choice C ($22) is also too low and does not account for the correct discount amount. Choice D ($69) is close but does not reflect the correct calculation after the 15% discount.
