$\frac{28 -(-18)}{2}$ - $\frac{15 -(-2)6}{3}$
= $\frac{46}{-2} - \frac{15 -(-2)6}{3}$
= 23 - $\frac{27}{3}$
= -23 - 9 = -32

- A factory assembles computers and normally produces 600 in x days.
i) Write down an expression involving x for the number produced per day(Solved)
A factory assembles computers and normally produces 600 in x days.
i) Write down an expression involving x for the number produced per day
ii) The rate of production is increased so that 600 are now produced in one day less (x -1). Write down an expression involving x for the number produced
iii) If the difference between these daily rates of production is 50, form an equation in x and show that it reduces to x2 - x - 12 = 0
iv) Hence find the number produced per day
