Answer:

Step-by-step explanation:
Order the numbers from lowest to highest.

There are eight numbers.
Mean of 68 and 70 is 69.
Therefore, median is 69.
Answer:
a=7
Step-by-step explanation:
step one: divide both sides by 2
now you will have 
step two: divide 14 by 2
14/2 is 7 so a is equal to 7
Answer:
The point (-8,-10) lies in the third quadrant of the graph.
Step-by-step explanation:
I graphed the point below to show that it is in the third quadrant.

Do you mind if I re-arrange it slightly before we solve it ?
You said 20x + 3.00y ≥ 500
Subtract 20x
from each side: 3.00 y ≥ -20x + 500
Divide each side by 3 : y ≥ -20/3 x + 500/3
Make it an equation,
and graph this line: y = -20/3 x + 500/3
The line is made out of all points where 'y' is EQUAL to
1/3 of (-20x + 500).
The inequality wants to see all the points that are equal to it
AND all the points that are greater than that.
So the graph of the inequality is the line AND every point that's
anywhere above the line. It's called the "half-infinite plane"
bounded by the line.
