Question 2

Algebraic expressions for the following are:

Question 2a - b - multiple choice question

a	x is divided by 3, and 2 is added to it.
	\(\dfrac{3}{x}\) + 2	\(\dfrac{x}{3}\) + 2	\(\dfrac{x + 2}{3}\)
b	z is multiplied by 6 and 7 is subtracted from the result.
	6 × z – 7	7 – 6 × z	6 – 7 × z
c	The quotient when p is divided by q.
	\(\dfrac{q}{p}\)	\(\dfrac{p}{q}\)	\(p × q\)
d	3 is multiplied by x and 2 is added to the result.
	2 × x + 3	3 × 2 + x	3 × x + 2

Question 3
