Because there is no whole number that you can divide into both the numerator and the denominator to get a proper fraction.
We already know that C = 45. All we really need to do is simplify the equation and then solve for x.
45 = x + 0.06x + 0.08x + 0.1x
45 = (1 + 0.06 + 0.08 + 0.1)x
45 = 1.24x
x = 36.2903, which rounds to $36.29 for the haircut.
Hello
by identity : a²-b² = (a-b)(a+b)
m²-25 = m²-5² (m-5)(m+5)
<span>x+7 <4
Subtract 7 from both sides so that the only thing remaining on the left side is the x variable.
Final Answer: x<= -3</span>
