 #### Question 2

Algebraic expressions for the following are:

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