How much money do I need to make to still have 1,000,000 left after 27.4% tax is removed?
Rama09 [41]

let's say the amount is "x", hmmm how much is 27.4% of "x"?   well

\bf \begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{27.4\% of x}}{\left( \cfrac{27.4}{100} \right)x}\implies 0.274x

so then, we know that x - 0.274x = 1000

\bf x - \stackrel{\textit{27.4\% of "x"}}{0.274x}=1000\implies 0.726x=1000\\\\\\ x = \cfrac{1000}{0.726}\implies x\approx 1377.41

2x-x+7 = x+3+4 is it no solution, one solution. or multiple solution if one of 2 please tell me what is x
ololo11 [35]

Answer:

x = x

Step-by-step explanation:

Basically, if you simplify the equation, you'll get x + 7 = x + 7 which means x = x which means you will have an infinite amount of solutions since x can be anything.
