Answer:
80
Step-by-step explanation:
Sum of interior angles of a polygon = (n-1)x180= (6-2)x180=720
Since this looks like a regular hexagon each interior angle =720/6=120
Hence the inside angle touching the line is 120 (inside the hexagon)
Since one side of the hexagon is parallel to the line, y and 20 form adjacent angle, sum 180,
Then y= 180-20=160
Then x=360-(160+120)=80 because sum of all angles round a point=360
Answer:
2.2y-2x = 0
Step-by-step explanation:
The standard form of the equation is normally y = mx + c where m is the gradient or the slope value while c is the y intercept.
As we know, the line passes through the origin, hence, it has no y intercept. This means our c has a value of zero.
What is left to find is the slope of the line.
m = (y2 - y1)/(x2 - x1)
m = (2 - 0)/(5 - 2.8)
m = 2/2.2 = 0.9091
so the standard form of the equation of the line is y = 0.9091x
OR
y = (2/2.2)x
OR
2.2y = 2x

Answer:
1.2 trains for $25.
Step-by-step explanation:
For 50 dollars, you could get 2.4 trains with the $25 dollar option.
For 90 dollars (an extra 40 dollars!) you only get 0.2 more trains.
If you add another $25 to the current $50 on the other option, you get 3.6 trains.
So, 1.2 trains for $25 must be the better option as you can get an extra 1 train for 15 dollars less!
Hope this helps!
Also, who buys 0.2 or 0.6 of a train? -_-
