If each hour 5 students receive a message at what time will 15,625 students receive a text messages

3125 hours

Explanaition:

Explanaition:First: Arrange the givens like this

1hr - 5students - 1 text

This is the first given

It says that after each hour 5 students receive a text.

Now the second given

x hours - 15,625 students - 1 text

Here we are saying that after x hours 15,625 students received 1 text.

So it should look something like this:

1hr - 5students - 1 text

xhr - 15,625 students - 1 text

Secondly: See how many minutes (time) would take for one student to receive a text.

so: 5students - 60 minutes (1 hr =60min)

1student - x minutes

cross multiply you get 60÷5= 12 min

Thirdly:

convert the minutes to hours by dividing 12 by 60, you get 0.5 hours

1student - 0.5 hours

15,625students - x

cross multiply you get

(15,625×0.5)÷1= 3125×1= 3125 hours

x/3-10=8

x/3=18

x=48

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
