Let h equal the number of hours the electrician works.

We can write the equation like this:

90h + 60 = 600

Solve for h.

90h + 60 = 600

~Subtract 60 to both sides

90h + 60 - 60 = 600 - 60

~Simplify

90h = 540

~Divide 90 to both sides

90h/90 = 540/90

~Simplify

h = 6

Therefore, the electrician work for 6 hours.

The correct answer is Option 1.

Best of Luck!

weeeeeb [17]

Answer:

x = number of days

y = number of remaining photos saved to her camera roll.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The number of pictures saved in the camera roll (2,500) minus the amount of photos that she deletes per day (50) multiplied by the number of days (x) must be equal to the number of photos remaining.

y =2,500- 50x

The variables are x and y.

Where x is the number of days and y is the number of remaining photos.
