7 Roni wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to 25 7 She writes the equation Y = X+ 25 What error is Roni making? 7 She should have written V=-X+ 25 so that x and y have a constant sum. 7 O She should have written XY = 25 so that x and y have a constant product. 7 X O She should have written Y = 25 so that x and y have a constant quotient. 7 She should have written Y = 25 so that y has a constant value.​

24/56=hx^7

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

step-by-step explanation:

infinity is the answer

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
