Answer:
Step-by-step explanation:
![a_n = n + 2](https://tex.z-dn.net/?f=a_n%20%3D%20n%20%2B%202)
![a_1 = 1 + 2 = 3\\a_2 = 2 + 2 = 4\\a_3 = 3 + 2 = 5](https://tex.z-dn.net/?f=a_1%20%3D%201%20%2B%202%20%3D%203%5C%5Ca_2%20%3D%202%20%2B%202%20%3D%204%5C%5Ca_3%20%3D%203%20%2B%202%20%3D%205)
It can be called a "percentage."
10/100 of a whole is 10% of it.
Answer: B
Step-by-step explanation: divide 75 by 25 to find how many feet you travel in 1 second (75/25=3) then you take 3 times 10 to see how many feet you travel in 10 seconds (3x10=30).
please use my image as a reference (figure not drawn to scale).
AB is a straight line and the angle of a straight line = 180°
so that means
, solve for
:
combine like-terms
![5x+x=180-6\\6x=174\\x=\frac{174}{6}](https://tex.z-dn.net/?f=5x%2Bx%3D180-6%5C%5C6x%3D174%5C%5Cx%3D%5Cfrac%7B174%7D%7B6%7D)

if you want to make sure of the answer, plug in
in the equation:
![5x+(6+x)=180\\5(29)+(6+29)=180\\145+35=180\\180=180](https://tex.z-dn.net/?f=5x%2B%286%2Bx%29%3D180%5C%5C5%2829%29%2B%286%2B29%29%3D180%5C%5C145%2B35%3D180%5C%5C180%3D180)
X= -1/3 or as an alternative form x=-0.3 and x=-3 exponent minus 1
