  1. If 3x - 7 = 14, what is the value of x?

    Answer: 7

    Add 7 to both sides: 3x = 21. Divide both sides by 3: x = 7. Verify: 3(7) - 7 = 21 - 7 = 14.

  2. A store offers a 20% discount on a $45 item. What is the sale price?

    Answer: $36

    20% of $45 = 0.20 × $45 = $9 discount. Sale price = $45 - $9 = $36.

  3. What is the next number in the pattern: 2, 6, 18, 54, ___?

    Answer: 162

    Each number is multiplied by 3: 2×3=6, 6×3=18, 18×3=54, 54×3=162. This is a geometric sequence with a common ratio of 3.

  4. If the perimeter of a square is 48 cm, what is its area?

    Answer: 144 sq cm

    Perimeter = 4 × side, so side = 48 ÷ 4 = 12 cm. Area = side² = 12² = 144 square centimeters.

  5. Which fraction is equivalent to 0.375?

    Answer: 3/8

    0.375 = 375/1000. Simplify by dividing both by 125: 375÷125 = 3, 1000÷125 = 8. So 0.375 = 3/8.

  6. A bag contains 4 red marbles, 3 blue marbles, and 5 green marbles. What is the probability of randomly selecting a blue marble?

    Answer: 1/4

    Total marbles = 4 + 3 + 5 = 12. Probability of blue = 3/12 = 1/4.
