Jorge’s monthly bill from his internet service provider was $25. the service provider charges a base rate of $15 per month plus $1 for each hour that the service is used. find the number of hours that jorge was charged for that month.

10 hours

Step-by-step explanation:

Let us suppose the number of hours that Jorge was charged for that month was x hours.

Now, service provider charges $1 for each hour that the service is used.

Thus, amount for using x hours should be 1x = $x

now, the base rate is $15 per month. Hence, total cost should be x + 15

Now, it has been given that Jorge’s monthly bill from his Internet service provider was $25.

Therefore, we have the equation

x + 15 = 25

Subtract 15 to both sides

x = 25 - 15

x = 10

Thus, Jorge was charged for 10 hours.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
