B. 3x-2y=6 would be the correct answer
20. Using absolute value, make (-10) turn into 10 and do 10 + 10 = 20
We know all these angles combined equals 360, so:
3x + 20 + 3x + 20 + x + x = 360
8x + 40 = 360
8x = 320
x = 40
Hope this helps!
Answer:
c=2
Step-by-step explanation:
7-4c=3c-7
7+7=3c+4c
14=7c
Dividing both sides by 7
c=2
CHECK:
Putting c in the above equation
7-4(2)=3(2)-7
7-8=6-7
-1=-1
Hence the above solution satisfies the given equation
Answer: Yes. When you solve your equations, you're solutions will change a little bit. It's good because it'll give you the right answer.
I hope this helps you and I hope it's right. ☺
