Answer:
Step-by-step explanation:
![\text{Replace } [-8x] \text{ for } [y]\\\rightarrow [2x+4(-8x)=0]\\\\\text{Solve}\\[2x-32x=0]\\[-30x=0]\\= [0]](https://tex.z-dn.net/?f=%5Ctext%7BReplace%20%7D%20%5B-8x%5D%20%5Ctext%7B%20for%20%7D%20%5By%5D%5C%5C%5Crightarrow%20%5B2x%2B4%28-8x%29%3D0%5D%5C%5C%5C%5C%5Ctext%7BSolve%7D%5C%5C%5B2x-32x%3D0%5D%5C%5C%5B-30x%3D0%5D%5C%5C%3D%20%5B0%5D)
Tan(3x) = 1
3x = arctan(1) = pi/4, -3pi/4
x = (pi/4)/3 = pi/12 or (-3pi/4)/3 = -pi/4
Therefore, x = pi/12 or -pi/4
Answer:

Step-by-step explanation:
u have to divided and then subtract
Answer:
6.8
Step-by-step explanation:
8 * 6 = 48 (to reverse dividing by 6 to basically un-average the 6 numbers).
5 * 4 = 20 (to un-average these numbers as well).
48 + 20 = 68
68 / 10 = 6.8
Basically by doing this you are still adding all the numbers together & then dividing by 10 as if you added them all up at once & not in a group of 6 & a group of 4.
Hope this helped. :)
Once Youu Divide It Youu Go 524/9=58.222222... A lot Of 2's..
Hope This Helps Youu
Youur Welcome
