Answer:
x-30
Step-by-step explanation:
Firstly, you do the first step, which is, 3x-18+4x+12-6x, then you continue simplifying it: 7x-18+12-6x.
Keep it on and on, the next step: x-18+12, add 18 and 12 together you get 30.
So the final answer is x-30
Answer:
x= 1÷4
Step-by-step explanation:
2x - 6x + 1 =0
-4x + 1= 0
-4x = -1
The circumference is 72.22. The formula for circumference is the diameter times pi, which in this case multiplies to about 72.22
