TEAS Exam Math Practice

Correct Answer: C

Rationale: To solve the equation 5(4x - 5) = (3/2)(2x - 6), first distribute on both sides to get 20x - 25 = 3x - 9. Then, move x terms to one side and constants to the other side to get 17x = 16. Finally, divide by 17 to find x = 16/17, which is the correct answer (C). The other choices are incorrect because they do not yield the correct value of x when substituted back into the original equation.

Correct Answer: B

Correct Answer: C

Rationale: To find the perimeter of a rectangle, we add up all four sides. Given length = 12 cm, width = 5 cm. Perimeter = 2(length) + 2(width) = 2(12) + 2(5) = 24 + 10 = 34 cm. Therefore, the correct answer is C (34 cm). Choice A (17 cm) is incorrect, as it only considers the length and width separately. Choice B (24 cm) is incorrect, as it only adds the length and width once each. Choice D (40 cm) is incorrect, as it incorrectly doubles both the length and width.

Correct Answer: D

Rationale: To calculate Matt's new wage, we need to add the 3/20 increase to his original wage w. So, the new wage is w + 3/20w = 23/20w = 1.15w, which corresponds to choice D. Choice A is incorrect as it represents a decrease. Choice B is incorrect as it represents a smaller increase. Choice C is incorrect as it represents a larger increase than what Matt received.

Correct Answer: B

Rationale: To find the amount earned in 2 months, divide the total earned in 7 months by 7 to get the monthly amount. $15,036 / 7 = $2,148 earned per month. Then, multiply this monthly amount by 2 to find the earnings in 2 months: $2,148 * 2 = $4,296. Therefore, choice B ($4,296) is correct. Choices A, C, and D are incorrect because they do not follow the correct calculation steps and do not result in the accurate amount earned in 2 months.
