TEAS Test Practice Math

Correct Answer: A

Rationale: To simplify the given expression, combine like terms with the same variables. The expression 5x - 2y + 4x + y simplifies to 9x - y. Combine the x terms (5x + 4x = 9x) and the y terms (-2y + y = -y) to get 9x - y. This is the simplest form of the expression. The other choices are incorrect because they do not correctly combine the like terms or do not simplify the expression to its simplest form. Option B incorrectly subtracts 3y instead of y. Option C incorrectly adds 3y. Option D is not a simplified form of the expression as it lists x and y separately without combining like terms. So, the correct answer is A: 9x - y.

Correct Answer: B

Rationale: To calculate the total amount paid with financing: $1000 (down payment) + ($120/month * 12 months/year * 2 years) = $1000 + $2880 = $3880 To find out how much more he would pay with financing: $3880 - $1000 (if paid in one payment) = $2880 Therefore, the man would pay $2880 more with the financing plan, which aligns with choice B: $1280 more. Choices A, C, and D are incorrect as they do not accurately reflect the additional amount paid compared to paying in one payment.

Correct Answer: B

Rationale: To calculate the total height of the stacked bookcases, you add the heights of the two bookcases together. The larger bookcase is 14 inches tall, and the smaller one is 8 inches tall. Adding them gives us 14 + 8 = 22 inches. Therefore, the correct answer is B: 22 inches tall. Choice A: 12 inches tall - Incorrect because it doesn't account for the height of the larger bookcase. Choice C: 35 inches tall - Incorrect because it adds the heights of the two bookcases incorrectly. Choice D: 41 inches tall - Incorrect because it adds the heights of the two bookcases incorrectly.

Correct Answer: A

Rationale: To find the actual distance in miles, multiply the map distance by the scale factor. 3.2 inches * 45 miles/inch = 144 miles. Choice A is correct because it correctly applies the scale factor. Choices B, C, and D are incorrect because they do not properly calculate the actual distance using the scale provided on the map.

Correct Answer: B

Rationale: To calculate 80% of 30 questions, multiply 30 by 0.80, which equals 24. Joshua needs to answer at least 24 questions correctly to meet the 80% threshold for the scholarship. Therefore, the correct answer is B. Choice A (23) is incorrect because it falls short of 80% of 30 questions. Choices C (26) and D (27) exceed the minimum requirement, making them unnecessary.
