4/5 ,8/10, 16/20,
You multiply both numbers with the same number.
For ex. 4×2=8 5×2=10 so we have 8/10
Answer:
ok so first we need to find the area of the circle inside which is a=Pi*raduis^2
a=pi*1(radius is half of diamater)
a=3.14
ok then the area of the sqare including the circle is 16 so
16-3.14=12.86
this is is aprox since the area of pi is infinite and i just used 3.14
Hope This Helps!!!

First, I add all of my prices together.
$9.50(2)+$7.95+$7.95+$49.95= $84.85
Change 6% to a decimal = .06
Then multiply: 84.85 x .06 = $5.09
$5.09 is the sales tax
$84.85 + $5.09 = $89.94
Answer: $89.94
I hope this helps :)
Answer:
![x=8](https://tex.z-dn.net/?f=x%3D8)
Step-by-step explanation:
First, subtract 50.45x from both sides. Then divide by 7.5 on both sides.
![60+50.45x=57.95x\\60=7.5x\\x=8](https://tex.z-dn.net/?f=60%2B50.45x%3D57.95x%5C%5C60%3D7.5x%5C%5Cx%3D8)
