Grades 6/7Non-calculator
  1. Question 1. Solve 2x - 3 < 9

    Show worked answerHide worked answer
    1. M1: add 3 to both sides, 2x < 9 + 3
    2. A1: x < 6
    Answer: x < 6
    Solving Single Inequalities
    [2 marks]
  2. Question 2. Make x the subject of y = 2x² + 7
    x is positive.

    Show worked answerHide worked answer
    1. M1: subtracts 7 from both sides, giving y - 7 = 2x²
    2. M1: divides by 2, giving x² = dfracy - 72
    3. A1: takes the square root, giving x = sqrtdfracy - 72
    Answer: x = sqrtdfracy - 72
    Rearranging Harder Equations

  3. Question 3. An estimate of the number of newts in a pond is 400.
    The estimate was found by marking 50 newts in the first catch.
    In the second catch there were 32 newts, some of which were marked.
    Work out how many newts in the second catch were marked.

    1. M1: 400 = 50 × 32 ÷ c
    2. M1: c = 50 × 32 ÷ 400
    3. A1: 4
    Answer: 4

  4. Question 4. p is inversely proportional to the square root of q.
    p = 6 when q = 25.
    Find the value of p when q = 36.
