Answer:-7/4
Step-by-step explanation:
2(x-2)=6x+2-2(-2x-4)
Open brackets
2x-4=6x+2+4x+8
Collect like terms
-4-2-8=6x+4x-2x
-14=8x
Divide both sides by 8
-14/8=8x/8
-7/4=x
x=-7/4
Answer:
60
Step-by-step explanation:
you multiply 150*4 then divide that by 10 and that's your answer
Answer: ![x=80](https://tex.z-dn.net/?f=x%3D80)
Step-by-step explanation:
By definition, the sum of the exterior angles of a polygon is 360 degrees.
Knowing this, you can write the following equation:
![(x+8)+(2x+12)+(x+20)=360](https://tex.z-dn.net/?f=%28x%2B8%29%2B%282x%2B12%29%2B%28x%2B20%29%3D360)
Then, you must solve for "x" in order to find its value. To do it, you can follow these steps:
1. You need to add the like terms:
![(x+8)+(2x+12)+(x+20)=360\\\\4x+40=360](https://tex.z-dn.net/?f=%28x%2B8%29%2B%282x%2B12%29%2B%28x%2B20%29%3D360%5C%5C%5C%5C4x%2B40%3D360)
2. Now, subtract 40 from both sides of the equation:
![4x+40-(40)=360-(40)\\\\4x=320](https://tex.z-dn.net/?f=4x%2B40-%2840%29%3D360-%2840%29%5C%5C%5C%5C4x%3D320)
3. Finally, you must divide both sides of the equation by 4. Then:
![\frac{4x}{4}=\frac{320}{4}\\\\x=80](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B4%7D%3D%5Cfrac%7B320%7D%7B4%7D%5C%5C%5C%5Cx%3D80)
Answer:
has to be letter b because they connect and then separate opposite sides
