N is -4 because -4x2=-8 and -8+3=-5
Answer:
The third option: x= ![\frac{8}{3} \pi](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B3%7D%20%5Cpi)
Step-by-step explanation:
Arc length formula=![\frac{Central Angle}{360} * 2\pi r](https://tex.z-dn.net/?f=%5Cfrac%7BCentral%20Angle%7D%7B360%7D%20%2A%202%5Cpi%20r)
Arc length = ![\frac{120}{360} *2\pi (4)](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B360%7D%20%2A2%5Cpi%20%284%29)
=![\frac{8}{3}\pi](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B3%7D%5Cpi)
Answer:
48
Step-by-step explanation:
first multiply both 4 and 3 by 2
(4 x 2) x (3x 2)
then solve within the parenthisies
8 x 6
lastly 8 x 6=
48
Jill spent 19 1/4 hours doing homework last week.
Answer:
Yes they are equivalent, both equations equals ![15d+20](https://tex.z-dn.net/?f=15d%2B20)
Step-by-step explanation:
We first simplify Olivia's equation
![6d + 8 + 9d + 12](https://tex.z-dn.net/?f=6d%20%2B%208%20%2B%209d%20%2B%2012)
1. we combine like terms in the equation: ![6d + 8 + 9d + 12](https://tex.z-dn.net/?f=6d%20%2B%208%20%2B%209d%20%2B%2012)
![6d+9d](https://tex.z-dn.net/?f=6d%2B9d)
![8+12](https://tex.z-dn.net/?f=8%2B12)
![15d+20](https://tex.z-dn.net/?f=15d%2B20)
Now we simplify Isabella's
![5(3d + 4)](https://tex.z-dn.net/?f=5%283d%20%2B%204%29)
1. we do distributive property
![5*3d](https://tex.z-dn.net/?f=5%2A3d)
![5*4](https://tex.z-dn.net/?f=5%2A4)
![15d+20](https://tex.z-dn.net/?f=15d%2B20)
