Eighteen could be in standard form 18 or expanded form 10 + 8.
You could change 0.393 to a fraction by putting it over 1000
in this case put it over 0.393= 396/1000
the / is the fraction
it is 396 over 1000
Answer:
D. 
Step-by-step explanation:
We graph the points on the graph. The graph is attached.
Let us take two points (1, 14) and (15, 1), and calculate the slope
between them <em>(we choose these points because the line passing through them will be the best fit for all points) </em>

Thus we have the equation

Let us now calculate
from the point 


So the equation we get is

Let us now turn to the choices given and see which choice is closest to our equation: we see that choice D.
is the closest one, so we pick it.
Average speed is 12.6 miles per hour
<em><u>Solution:</u></em>
Given that team tool bella canoed
miles in
hours
To find: average rate of speed in miles per hour
From given information,


To find the speed we use the below formula,

Substituting the given values we get,

Thus average speed is 12.6 miles per hour
