7
(a) Simplify \(5p \times 9k\) (1)
(b) Simplify \(3e + 2f + 8e - 7f\) (2)
(c) Solve \(2d + 7 = 16\) (2)
| Scheme | Marks |
|---|---|
| \(45pk\) | B1 |
| (1) |
Notes
B1: accept \(45kp\)
| Scheme | Marks |
|---|---|
| \(11e - 5f\) | B2 |
| (2) |
Notes
B2: for \(11e - 5f\)
(B1 for \(11e\) or \(-5f\))
| Scheme | Marks |
|---|---|
\(2d = 16 - 7\) or \(2d = 9\) or \(d + \dfrac{7}{2} = \dfrac{16}{2}\) oe or (16 – 7) ÷ 2 or 9 ÷ 2 | M1 |
| Correct answer scores full marks (unless from obvious incorrect working) Answer: 4.5 | A1 |
| (2) | |
| (5 marks) |
Notes
A1: accept \(\dfrac{9}{2}\) or \(4\dfrac{1}{2}\)
