(n - 2)180 = sum of angles (six sides)
(6 - 2)180 = y
(4) 180 = y
720= y
115+110+x+25+x-30+x+x = 720
4x + 220 = 720
4x = 720 - 220
4x = 500
x = 500/4
x = 125
y=3x-13 is equation of the line that is parallel to the line 3x - y = 2
and passes through (6,5).
Answer:

Step-by-step explanation:
Let
x------> Lamar's collection of cards
The algebraic expression of the phrase "Lamar decreased his collection of cards by seven" is equal to subtract the number seven from Lamar's collection of cards
so
