Diagram not drawn to scale
Calculate the value of \(x\).
You must show all your working. [3]
| Scheme | Marks | Comments |
|---|---|---|
| \(2(x) + 3(x) + 4(x)\) OR \(9(x)\) AND 360 | B1 | |
| \((x =)\) 360 ÷ 9 | M1 | FT ‘their 360’ ÷ 9 or 360 ÷ ‘their 9’ provided ‘their 9’ > 4. |
| 40 | A1 | CAO Award B1M1A1 for a trial and improvement method where the final attempt is correct and not contradicted by \(x \neq 40\) |
Corrected by Westie's Workshop
- The board's mark scheme printed “a trail and improvement method”. Changed to “a trial and improvement method” because the method is called trial and improvement.
Original: see the board's mark scheme PDF (link above).
