6:5. or 6/5 which ever way you choose
Answer:
D. 16
Step-by-step explanation:
Average rate of change: 
Simply plug in 6 for <em>a</em> and 2 for <em>b</em>
<em />
Graph a... you go down on the y axis 3, and then using the rise over run method, you go up 3, over 4
Well...it says the sum of the angles measure 360...so lets set them equal to 360
40 + x - 10 + 1/3x + x - 20 = 360...combine like terms
2 1/3x + 10 = 360
7/3x = 360 - 10
7/3x = 350
x = 350/(7/3)
x = 350 * 3/7
x = 1050/7
x = 150 <=====
