-2-w is equivalent to -24 - 12w all you have to do is simplify the expression!
A unit rate where one is in the Denometer, so you would want to divide the bottom by 10.
The answer is 4.
There were in total 96 pictures (84 pictures + 12 spoiled = 96 pictures).
1 roll of film has 24 pictures. x rolls of film have 96 pictures.
1 : 24 = x : 96
x = 1 * 96 : 24
x = 4
The ordered pair (7, 19) is only a solution to the first equation, 14-19= -5. the ordered pair is not a solution to the second equation 7 + 57 does not equal 22.

Answer: 1260</h3>
====================================================
Work Shown:
n = number of sides = 9
S = sum of the interior angles of any polygon with n sides
S = 180(n-2)
S = 180(9-2)
S = 180(7)
S = 1260
