Answer:
So we have this equation:
2 (3x-2) - 4x = 5x + 2
You can first operate the parenthesis, knowing that a(b+c) = ab + ac (conmutative)
2(3x-2) - 4x = 5x + 2
2 * 3x - 2 * 2 - 4x = 5x + 2
6x - 4 -4x = 5x + 2
Now, we can operate the x:
6x - 4 -4x = 5x + 2
2x - 4 = 5x + 2
And sum 4 in both sides and substract 5x in both too.
2x - 4 = 5x +2
2x - 4 + 4 - 5x' = 5x + 2 + 4 -5x
Now we can operate:
-3x = 6
And we can divide by -3 the two sides...
x = 6/-3 = -2

Answer:
c = 10 cm
Step-by-step explanation:
The circumference formula is C = πd. We want to solve this for the diameter, d:
C
d = -------
π
Substituting 31.4 cm for d, we get:
31.4 cm
d = -------------- = 10 cm, when 3.14 is used as an approximation for π/
3.14
