Answer:
0.3
Step-by-step explanation:
By definition: 30% = 30/100 = 0.3
The value of x in the equation 1/2x = -1/2x when 4 is subtracted from both sides is 0(not defined)
Subtraction of fraction
Startfraction one-half EndFraction x equals negative StartFraction one-half EndFraction
1/2x = -1/2x
- Subtract 4 from both sides
1/2x - 4 = -1/2x - 4
(x-8) / 2 = (-x-8) / 2
(x - 8) / 2 = (-x-8) / 2
2(x - 8) = 2(-x - 8)
2x - 16 = -2x - 16
2x + 2x = -16 + 16
4x = 0
