90-69=21 degrees. This is our target answer. We'll write an equation to do this:
2x-1=21
Add 1 to each side to get:
2x=22
Divide by 2 to get that x=11

Plugging this in, we see that 2(11)-1+69=90, so our answer is correct.

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.
