x = 18 minutes.

Step-by-step explanation:

We work in fraction of the work done per minute.

You rake 1/30th of the yard in 1 minute and your brother rakes 1/45 of the yard in 1 minute. So we have:

1/30 + 1 /45 = 1/ x  where x = time taken when working together.

Multiply through by the LCD ( = 90x):

3x + 2x = 90

5x = 90

x = 18 minutes.

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

2, 2, 2 or -4, 20, 29
