Answer:
D. 1/3
Step-by-step explanation:
Like I said, just use the formulas
y=2x is 2,4,6,8
y=3x+1 is 4,7,10,13
y=x-5 is -4,-3,-2,-1
y=5x+6 is 11,16,21,26
Wow I just noticed these are all patterns...
Then use the number more than twice, like 3 or 4 times
6x5+2÷9-4
30x+2/9-4
2/9-4
-34/9
30x-34/9
Supplementary: straight line is 180 degree
x + (x-6) = 180
2x = 186
X = 93
