  1. Find the value of x: 5(x - 2) = 3x + 4

    Answer: 7

    5x - 10 = 3x + 4 → 2x = 14 → x = 7.

  2. What is the equation of a line with gradient 3 and y-intercept -2?

    Answer: y = 3x - 2

    Using y = mx + c: gradient m = 3, y-intercept c = -2, so y = 3x - 2.

  3. A map has a scale of 1:50000. A distance of 4 cm on the map represents how many km in real life?

    Answer: 2 km

    4 cm × 50000 = 200000 cm = 2000 m = 2 km.

  4. Calculate the circumference of a circle with diameter 14 cm. (Use π ≈ 22/7)

    Answer: 44 cm

    C = πd = (22/7) × 14 = 44 cm.

  5. Solve the simultaneous equations: x + y = 7 and x - y = 3

    Answer: x=5, y=2

    Adding: 2x = 10, x = 5. Substituting: 5 + y = 7, y = 2.

  6. What type of triangle has all sides equal and all angles equal to 60°?

    Answer: Equilateral

    An equilateral triangle has all three sides equal and all three interior angles equal to 60°.
