Since there was a ray drawn from A through C the exterior angle of angle C is angle 1. Any straight line should equal to 180 degrees.
Answer:
(2, 5)
Step-by-step explanation:
Let the number of fancy throw pillows be x.
Let the number of plain throw pillows be y.
Hope spent a total of $131 on 7 throw pillows.
Fancy throw pillows cost $28 and plain throw pillows cost $15.
These imply two things:
x + y = 7 _______ (1)
28x + 15y = 131 ___(2)
We have a linear system of equations.
From (1):
x = 7 - y
Substitute the value of f into (2):
28(7 - y) + 15y = 131
196 - 28y + 15y = 131
196 - 13y = 131
=> 13y = 196 - 131
13y = 65
y = 65 / 13
y = 5
This means that:
x = 7 - 5 = 2
Hope bought 2 fancy throw pillows and 5 plain throw pillows

Answer:
given,
Amount borrowed = $71500
Time = 200 days
interest rate = 7.5 %
ordinary interest rate for year = ![71500\times \dfrac{7.5}{100}](https://tex.z-dn.net/?f=71500%5Ctimes%20%5Cdfrac%7B7.5%7D%7B100%7D)
= $5362.5
exact interest rate for the year = ![71500\times \dfrac{7.5}{100}\times \dfrac{200}{365}](https://tex.z-dn.net/?f=71500%5Ctimes%20%5Cdfrac%7B7.5%7D%7B100%7D%5Ctimes%20%5Cdfrac%7B200%7D%7B365%7D)
= $2938.35
hence, the exact interest rate is less than the ordinary interest rate which means you should choose exact interest rate.
Good luck :))))))))))))))
