Part (a) · 2 marks
Simplify 10x − 7y − 6x + 4y by collecting like terms.
- 110x − 6x = 4x
- 2−7y + 4y = −3y
- 34x − 3y
Answer4x − 3y
Part (b) · 2 marks
Find T when d = 13 and e = 7 in T = 4d − 6e.
- 14 × 13 = 52
- 26 × 7 = 42
- 352 − 42 = 10
Answer10
Part (c) · 2 marks
Solve 5p + 11 = 28 for p.
- 128 − 11 = 17
- 25p = 17
- 3p = 17/5
Answer17/5
