Patterns are made using straight lines and arcs. a) Pattern A (one row) Pattern B (two rows) (2) More rows are added to Pattern B so that number of straight lines : number of arcs = 7: 6 How many rows are added? Your final line must say, ... rows are added to B b) A different pattern is made using 20 straight lines and 14 arcs. The straight lines and arcs are made from metal. 20 straight lines cost £12 cost of one straight line: cost of one arc = 2:3 Work out the total cost of metal in the pattern.

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
