A person can do a job in 6 days. Another can do the same job in 4 days. If they work together, how long do they need to finish the job?

12/5 days

Step-by-step explanation:

if d=number of days

w=work completed

person one completes w=d/6 (ie. after 6 days (when d=6) work will be completed (w=1))

person two completes w=d/4 (ie. after 4 days (when d=4) work will be completed (w=1))

so total work competed together w=d/6 + d/4

the job is complete when w=1 so

1 = d/6 + d/4

12 = 2d + 3d

12 = 5d

d = 12/5

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )

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
