Solve the system of equations.
Equation 1: 2x + y = 0
Equation 2: x - 2y = 8

  • A. (1.8, 3.6) and (-1.8, -3.6)
  • B. (1.8, -3.6) and (-1.8, 3.6)
  • C. (1.3, 2.6) and (-1.3, -2.6)
  • D. (-1.3, 2.6) and (1.3, -2.6)
Correct Answer: B

Rationale: From Equation 1: 2x + y = 0. Solve for y: y = -2x. Substitute y = -2x into Equation 2: x - 2(-2x) = 8. Simplify to x + 4x = 8, then 5x = 8, and x = 8 · 5 = 1.6. Substitute x = 1.6 back into y = -2x to find y = -3.2. Therefore, one solution is (1.6, -3.2). To find the second solution, use -1.6 for x to get (-1.6, 3.2). Thus, the correct answer is B, representing the solutions (1.8, -3.6) and (-1.8, 3.6). Choices A, C, and D contain incorrect values that do not match the solutions derived from solving the system of equations.

What is the mode of the data set: 2, 3, 3, 4, 4, 4, 5?

  • A. 2
  • B. 3
  • C. 4
  • D. 5
Correct Answer: C

Rationale: The mode of a data set is the value that appears most frequently. In this data set (2, 3, 3, 4, 4, 4, 5), the number 4 appears three times, which is more frequent than any other number in the set. Therefore, the correct answer is 4. Choice A (2), B (3), and D (5) do not appear as frequently as 4 in the data set, so they are not the mode.

How many kiloliters are in 147 liters?

  • A. 0.147 kiloliters
  • B. 1.47 kiloliters
  • C. 1,470 kiloliters
  • D. 147,000 kiloliters
Correct Answer: A

Rationale: To convert liters to kiloliters, divide by 1000 since there are 1000 liters in a kiloliter. Therefore, 147 liters = 0.147 kiloliters. Choice B is incorrect as it incorrectly moves the decimal point. Choices C and D are significantly larger than the correct answer, indicating an incorrect conversion factor used.

What is the result of dividing 8 by 4?

  • A. 2
  • B. 4
  • C. 6
  • D. 8
Correct Answer: A

Rationale: To find the result of dividing 8 by 4, we divide 8 by 4, which equals 2. Choice B (4) is incorrect because it is the divisor, not the result of the division. Choice C (6) is incorrect as it is not the correct quotient. Choice D (8) is incorrect as it is the dividend, not the result of the division.

What is the perimeter of a square with a side length of 6 cm?

  • A. 24 cm
  • B. 12 cm
  • C. 18 cm
  • D. 36 cm
Correct Answer: A

Rationale: The perimeter of a square is calculated by multiplying the side length by 4 since all sides are equal. In this case, the side length is 6 cm, so the perimeter is 4 * 6 = 24 cm. Therefore, choice A, 24 cm, is the correct answer. Choices B, C, and D are incorrect because they do not reflect the correct calculation for the perimeter of a square.

Solve the equation for the unknown. 3x + 2 = 20

  • A. x = 2
  • B. x = 4
  • C. x = 6
  • D. x = 8
Correct Answer: C

Rationale: Simplify the equation step by step:

Subtract 2 from both sides:
3x + 2 - 2 = 20 - 2
3x = 18

Divide both sides by 3:
x = 18 · 3
x = 6

Therefore, the correct answer is C (x = 6).
