Answer:
x > 77
Step-by-step explanation:
According to order of operations rules, we must carry out division before addition or subtraction. In this case we wish to isolate x and are permitted to simplify the inequality by combining the "like terms" 3 and 8, as follows:
X/7-3>8
+3 +3
--------------
x/7 > 11
The easiest way in which to solve for x is to multiply both sides of this inequality by 7:
7(x/7) > 7(11), or
x > 77
All numbers greater than 77 are part of the solution set.
The answer is B: Y
Y did not change position even after it is reflected
Well, for method one the first step we have is distribution, then combining like terms, then property of subtraction, then division. For method two, I'm not entirely sure what they did there. I've never done math like that. Sorry I can't help you out all the way.

Because the boarder goes around all edges, 6 in must be subtracted from 6ft and 4ft.
6ft - 6in = 5.5 ft
4ft - 6in = 3.5 ft
Area of the bulletin board: (5.5)(3.5) = 19.25 ft
Log 3^x = x log 3
x log 3 = 40
x = 40 / log 3
= 83.84 ( using logs to the base 10)
