Question

If her bill this month was $120 determine how many gigabytes she used this month by solving for x in the following equation:

-120= -5x - 50

O 22 gigabytes
O 14 gigabytes
O 34 gigabytes
O 10 gigabytes

Answer 1

To determine how many gigabytes she used this month, solve the equation -120 = -5x - 50 to find x.

Step-by-step explanation:

To determine how many gigabytes she used this month, we need to solve the equation:

-120 = -5x - 50

To isolate the variable x, we can start by adding 50 to both sides of the equation:

-120 + 50 = -5x

Next, we need to simplify:

-70 = -5x

Finally, we can solve for x by dividing both sides of the equation by -5:

x = -70 / -5 = 14

Therefore, she used 14 gigabytes this month.
