Examples
Angles 1 and 2 are adjacent angles because they share a common side.
adjacent angles examples
The factors are 1 and 47, since 47 is a prime number.
One variable is the amount of days. Lets call the amount of days D. Another variable is the amount of pictures left. Lets call this p. In this case, since Emanuel is deleting 20 pictures a day, and he has 745 picture to start with, the equation would be 745- 20D=p.
The range is a statistical property that consists of the difference between the biggest and the smallest given number.
In our case, the biggest is 17.3 million and the smallest is 3.3 million:
17.3 - 3.3 = 14.0
The range is 14.0 million acres (option D, 4th option).
