Answer:
measure of each angle of a regular octagon=360/8=45°
at the point, 60°+x+45=360°
x=255°
Answer:
0.0004
Step-by-step explanation:
2 3/5 divided by 6500
<span>Uphill distance = 1 4/5 = 9/5 = 18/10 km
Downhill Distance = 2 7/10 = 27/10 km
Total Uphill and Downhill = 18/10 + 27/10 = 45/10 = 4.5 km
Hence total level ground = Total race km - (Uphill + Downhill)
=10 - 4.5 = 5.5 km
Hence the answer is 5.5 km.</span>
Answer:
Part B: ![\displaystyle [1, 2]](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B1%2C%202%5D)
Part A: Set both equation equal to each other by Substitution, since our <em>y-values</em> are already given to us.
Step-by-step explanation:
6x - 4 = 5x - 3
- 6x + 3 - 6x + 3
____________

Plug this coordinate back into the above equations to get the <em>y-coordinate</em><em> </em>of 2.
<em>y</em><em> </em><em>=</em><em> </em><em>mx</em><em> </em><em>+</em><em> </em><em>b</em><em> </em>[where<em> </em><em>b</em><em> </em>is the y-intercept and the rate of change (slope) is represented by <em>m</em>]
![\displaystyle y = 5x - 3; [0, -3]; 5 = m \\ y = 6x - 4; [0, -4]; 6 = m](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y%20%3D%205x%20-%203%3B%20%5B0%2C%20-3%5D%3B%205%20%3D%20m%20%5C%5C%20y%20%3D%206x%20-%204%3B%20%5B0%2C%20-4%5D%3B%206%20%3D%20m)
