Answer:

En la última fila de la zona general hay 98 asientos y en la zona preferencial hay 564 asientos.

Explicación paso a paso:

40 = 20 + 40 − 1 × 2

40 = 20 + 39 × 2

40 = 20 + 78

40 = 98

=  (1 + )  2 ×

12=  (36 + 58)  2 ×12

12 = 47 × 12

12 = 564

umka2103 [35]
To find how long it will take to fill the tank, you can use the idea that every 30 seconds will get you one gallon closer to being full.

This means to fill 50 gallons, you will need 50 groups of 30 seconds.  

50 x 30 = 1500 seconds

1500/60 = 25 minutes.

It will take 25 minutes.  

You could also think of it as filling 2 gallons every minute.  It would take 25 of these.
