Answer:
Ms. Day bought 5 blankets and 4 pillows.
Step-by-step explanation:
Let
denotes number of blankets and
denotes number of pillows.
Blankets cost her $16 while pillows cost her $10 and Ms. Day spent a total of $120.
![16x+10y=120](https://tex.z-dn.net/?f=16x%2B10y%3D120)
Divide this equation by 2.
![8x+5y=60\,\,...(i)](https://tex.z-dn.net/?f=8x%2B5y%3D60%5C%2C%5C%2C...%28i%29)
Ms. Day bought 9 items.
![x+y=9](https://tex.z-dn.net/?f=x%2By%3D9)
Multiply this equation by 5.
![5x+5y=45\,\,...(ii)](https://tex.z-dn.net/?f=5x%2B5y%3D45%5C%2C%5C%2C...%28ii%29)
Subtract
from ![(i)](https://tex.z-dn.net/?f=%28i%29)
![3x=15\\x=5](https://tex.z-dn.net/?f=3x%3D15%5C%5Cx%3D5)
Put
in ![x+y=9](https://tex.z-dn.net/?f=x%2By%3D9)
![5+y=9\\y=9-5\\y=4](https://tex.z-dn.net/?f=5%2By%3D9%5C%5Cy%3D9-5%5C%5Cy%3D4)
Therefore,
Ms. Day bought 5 blankets and 4 pillows.

Step-by-step explanation:
I am really not good at this
Answer:
126
Step-by-step explanation:
By cyclic quadrilateral theorem:
![(180 \degree - 85 \degree) = \frac{1}{2} (z \degree + 64 \degree) \\ 95 \degree \times 2 = z \degree + 64 \degree \\ 190 \degree = z \degree + 64 \degree \\ 190 \degree - 64 \degree = z \degree \\ 126\degree = z \degree \\ z = 126](https://tex.z-dn.net/?f=%28180%20%5Cdegree%20-%2085%20%5Cdegree%29%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%28z%20%5Cdegree%20%2B%2064%20%5Cdegree%29%20%5C%5C%2095%20%5Cdegree%20%5Ctimes%202%20%3D%20z%20%5Cdegree%20%2B%2064%20%5Cdegree%20%5C%5C%20190%20%5Cdegree%20%3D%20z%20%5Cdegree%20%2B%2064%20%5Cdegree%20%5C%5C%20190%20%5Cdegree%20-%2064%20%5Cdegree%20%3D%20z%20%5Cdegree%20%5C%5C%20126%5Cdegree%20%3D%20z%20%5Cdegree%20%5C%5C%20z%20%3D%20126)
Answer:
20 sides.
Step-by-step explanation:
The exterior angle = 180 - 162 = 18 degrees.
Since the sum of the exterior angles = 360 degrees the number of sides
= 360 / 18
= 20 sides.
