Subtract ; 68 - 24 =44 so that means Sarah is 44 years old.
Theres 8 edges, 5 vertices, and 5 faces.
The two inequalities can be rewritten as
The solution is composed by every point below the graph of the line 
, and above the horizontal line 
To draw the line we can build a little table (only 2 points are required):
So, if you draw the points (0,2) and (1, -2) and connect them, you'll have your line.
To draw the line , simply pick any point with y coordinate -2, for example (0, -2), and draw a horizontal line.
Choose the above/below areas as specified above to solve the system.
Answer:
15 percent
Step-by-step explanation: You will substract the new value from the old value.

Now you will get the difference between them and divide that by the original amount.
3/20
This will equal 0.15 in which you now multiply by 100
15 percent
