Answer:
about 6000π
Step-by-step explanation:
If t represents the number of teeth in one row...and a shark has 3 rows of teeth...then the expression to find out how many teeth he has in his entire mouth is : 3t
The value of 
that satisfies all the expressions of the system of linear equations is 20.
<h3 /><h3>Procedure - Determination of a variable associated to a pair of corresponding angles</h3>
According to the figure, angles 1 and 5 are <em>corresponding</em> angles between two <em>parallel</em> lines, therefore we have the following equivalence:
(1)
After some algebraic handling we find the value of :
The value of that satisfies all the expressions of the system of linear equations is 20. 
<h3>Remarks</h3>
There is a missing figure for the statement, we proceed to include it below after some research.

A clock is a circle which is 360 degrees.
There are 12 hours -----> 360/12 = 30 degrees.
Going clockwise, add 30 degrees for every hour the hour hand is at.
There are 60 minutes -----> 360/60 = 6 degrees.
Add 6 degrees for every minute the minute hand is at.
Find position of both hour hand and minute hand, then take the difference.
Time is 5:15.
Hour hand is at 5 plus 15/60 or 5.25.
Multiply by 30. 30*5.25 = 157.5
Minute hand is at 15.
Multiply by 6. 15*6 = 90
157.5 - 90 = 67.5 degrees.
It would be D because the equation just seems flipped, but the requirements of x are fulfilled.
