TEAS Test Math Questions

Correct Answer: B

Rationale: To solve the system of equations, we can use either substitution or elimination method. By substituting y = -2x into the second equation, we get x - 2(-2x) = 8, which simplifies to 5x = 8, leading to x = 8/5. Substituting x back into the first equation, we find y = -16/5. Therefore, the correct solution is (1.6, -3.2). Option B (1.8, -3.6) and (-1.8, 3.6) is incorrect as it does not match the calculated solution. Options A, C, and D are also incorrect as they do not correspond to the solutions obtained through the correct calculations.

Correct Answer: C

Rationale: To solve 3x + 2 = 20, first subtract 2 from both sides to isolate 3x. This gives 3x = 18. Then divide by 3 to solve for x, yielding x = 6. Choice C is correct because 3(6) + 2 equals 20. Choices A, B, and D are incorrect because they do not satisfy the original equation when substituted back in.

Correct Answer: A

Rationale: To find the total distance Jayden rides, add the two distances: 5/8 + 3/4 = 10/16 + 12/16 = 22/16 = 1 6/16 = 1 3/8 miles. Therefore, choice A (1 3/8 miles) is the correct answer. Choices B, C, and D are incorrect because they do not accurately calculate the total distance Jayden rides based on the given distances.

Correct Answer: A

Rationale: To solve |x| = 10, we consider both possibilities: x = 10 and x = -10 since the absolute value of x is always positive. So, the correct answer is A: -10, 10. Choice B, C, and D are incorrect because they do not reflect the correct solutions to the absolute value equation given.

Correct Answer: A

Rationale: To convert liters to kiloliters, we divide by 1000 since 1 kiloliter is equal to 1000 liters. In this case, 147 liters divided by 1000 equals 0.147 kiloliters, so the correct answer is A. Choice B is 10 times the correct answer, choice C is 100 times the correct answer, and choice D is 1000 times the correct answer, making them incorrect.
