Foundation June 2022 Paper 1 Q8
8
(a) Simplify \(12g - 8e - 5g + 6e\) (2)
\(A = 3b - 5c\)
(b) Work out the value of \(A\) when \(b = 12\) and \(c = 4\) (2)
(c) Solve \(4p + 9 = 24\) (2)
| Scheme | Marks |
|---|---|
| \(7g - 2e\) | B2 |
| (2) |
Notes
B2: or \(-2e + 7g\)
If not B2 then award
B1 for \(7g\) or \(-2e\)
| Scheme | Marks |
|---|---|
| 3 × 12 (= 36) and 5 × 4 (= 20) | M1 |
| 16 | A1 |
| (2) |
Notes
A1: SC B1 for an answer of 56 or –16
| Scheme | Marks |
|---|---|
\(4p = 24 - 9\) or \(4p = 15\) or \(p + \dfrac{9}{4} = \dfrac{24}{4}\) oe or (24 – 9) ÷ 4 or 15 ÷ 4 | M1 |
| \(\dfrac{15}{4}\) | A1 |
| (2) | |
| (6 marks) |
Notes
M1: for a correct first step
or for a calculation for \(p\)
A1: oe e.g. 3.75 or \(3\dfrac{3}{4}\)
