Let's use a for number of days when he shot 50 shots and b for number of days when he shot 100 shots.
We have:
a + b = 20
We also know that he shot total of 1250 shots:
50a + 100 b = 1250
We have two equations. We can solve them for a and b. Let's rearange first equation for a:
a= 20 - b
We insert this into second equation:
50 * (20 - b ) + 100b = 1250
1000 - 50b + 100b = 1250
50b = 250
b = 5
a = 20 - 5
a = 15
Mark shot 100 shots on 5 days.
Farrah's total score for both rounds will be -3.
Since the leader board shows Farrah's score as 5 on the front nine, this will be: +5
Since the leader board shows Farrah's score as 8 on the back nine, this will be -8. Then we'll add both together to get the total score which will be:
= 5 + (-8)
= 5 - 8
= -3
His total score will be -3.

Answer:
The best estimate for the solution is the ordered pair 
Step-by-step explanation:
we have
------> equation A
------> equation B
we know that
using a graphing tool, the solution of the system of equations is the intersection point both graphs
The intersection point is 
therefore
The best estimate for the solution is the ordered pair
No, it does not have a straight line. (A)
