  1. What is the value of x in the equation 3x + 5 = 20?

    Answer: 5

    Subtract 5 from both sides to get 3x = 15, then divide both sides by 3 to get x = 5.

  2. A triangle has a base of 10 cm and a height of 6 cm. What is its area?

    Answer: 30 sq cm

    Area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 square centimeters.

  3. Which of the following is equivalent to 40%?

    Answer: 2/5

    40% = 40/100 = 2/5 when simplified by dividing both numerator and denominator by 20.

    2/3 × 3 = 6/3 = 2 cups of sugar.

  6. What is the mean (average) of the data set: 8, 12, 6, 14, 10?
