  • 𝑦 > 3.5. Write down the smallest integer that y could be
    4
  • 5(4𝑞 − 11 + 2𝑟) = ?
    16q - 44 - 8r
    16q + 44 + 8r
    16q + 8r
    16q - 44 + 8r
  • Apples cost a pence each. Bananas cost b pence each. Pence Write down an expression for the total cost, in pence, of 3 apples and 5 bananas.
    3a + 3b
    3b+5a
    5a + 5b
    3a + 5b
  • In the triangle ABC, the angle at A is (4k + 5m)°. The angle at B is two times the size of the angle at A. Write an expression, in its simplest form, for the size of the angle at B.
    2 x (4k+5m) = 8k + 10m
    2 x (4k+5m) = 8k - 10m
    3 x (4k - 5m) = 12k - 15m
    2 x (4k - 5m) = 8k - 10m
  • 𝑦 > 5. Write down the smallest integer that y could be
    6

    x/4
    4x
    x + 4
    x - 4
  • Pedro has striped, checked and spotted bricks. The length of a striped brick is x. The length of a checked brick is y. The length of a spotted brick is z. Work out the total length of each arrangement of bricks.
    2x + 2y + z
  • Kris goes out for a meal at a restaurant with four friends. They share the total cost of the meal equally between the six of them. Write a formula to work out the amount they each pay, in Words
    the amount they each pay = the total cost divided by 6
