Answer: x=5
x=−5
Step-by-step explanation:
Answer: X=6.
Step-by-step explanation:
16x-8+2x=100
18x-8=100
18x=100+8
18x=108
x=108/18
x=6
Answer:
The answer is "option c".
Step-by-step explanation:
Please find the complete question in the attached file.
The center angle of the CBD arc is equivalent to the arc:
![\to 300^{\circ} = \frac{5\pi}{3} \ radians\\\\](https://tex.z-dn.net/?f=%5Cto%20%20300%5E%7B%5Ccirc%7D%20%3D%20%5Cfrac%7B5%5Cpi%7D%7B3%7D%20%5C%20%20radians%5C%5C%5C%5C)
![\to 180^{\circ}\ is\ \pi \ radians, \ so \ (\frac{5 (180^{\circ})}{3})\\](https://tex.z-dn.net/?f=%5Cto%20180%5E%7B%5Ccirc%7D%5C%20%20is%5C%20%20%5Cpi%20%5C%20radians%2C%20%5C%20so%20%5C%20%28%5Cfrac%7B5%20%28180%5E%7B%5Ccirc%7D%29%7D%7B3%7D%29%5C%5C)
![= 300^{\circ} \\\\ = (\frac{5 \pi}{3}) \ radians](https://tex.z-dn.net/?f=%3D%20300%5E%7B%5Ccirc%7D%20%5C%5C%5C%5C%20%3D%20%28%5Cfrac%7B5%20%5Cpi%7D%7B3%7D%29%20%5C%20%20radians)
2+4z-18
change it so it's an equation
2+4z-18=0
then get 4z alone on one side by subtracting 4z from both sides
2-18=-4z
-16= -4z
divide both sides by -4
a negative divided by a negative becomes positive
4 =z
plug it in
2+4(4)-18
4x4 is 16
2+16-18=0
0=0
the same can be done for the second one 2+k-8
make it 2+k-8=0
move the k to get it alone so subtract k from both sides
2-8=-1k
-6 = -1K
you can divide by K to make K=6
plug in 2+6-8=0
0=0
I used to love math and now i hate it cuz of my math teacher lol
