TEAS Test Math Questions Questions
Question 1 of 5
What is the difference between two equal numbers?
Correct Answer: C
Rationale: The correct answer is C: Zero. When two numbers are equal, their difference is always zero. This is because the distance between two equal numbers on the number line is zero. Any other choice is incorrect because a negative or positive difference implies inequality, which contradicts the premise that the numbers are equal. Choice D is also incorrect as there is sufficient information to determine the difference between two equal numbers.
Question 2 of 5
Solve the system of equations. Equation 1: 2x + y = 0 Equation 2: x - 2y = 8
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.
Question 3 of 5
Which proportion yields a different number for the unknown compared to the others?
Correct Answer: D
Rationale: To determine the correct answer, we need to find the value of x in each proportion. For choice A, x = 4; for choice B, x = 8; for choice C, x = 6; and for choice D, x = 10. So, the correct answer is D because it yields a different value for x compared to the other choices. Choices A, B, and C all have x values that are multiples of 2, whereas choice D has a different x value. Therefore, choice D is the only proportion that yields a different number for the unknown compared to the others.
Question 4 of 5
How many kiloliters are in 147 liters?
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.
Question 5 of 5
What is the difference between two equal numbers?
Correct Answer: C
Rationale: The correct answer is C: Zero. When two numbers are equal, their difference is always zero. This is because the distance between two equal numbers on the number line is zero. Any other choice is incorrect because a negative or positive difference implies inequality, which contradicts the premise that the numbers are equal. Choice D is also incorrect as there is sufficient information to determine the difference between two equal numbers.
