64=(x+8)+90<br><br>what does x equal

Tomtit [17]

$Solution, solve\:for\:x,\:64=\left(x+8\right)+90\quad :\quad x=-34$

$Steps:$

$64=\left(x+8\right)+90$

$\mathrm{Switch\:sides}, \left(x+8\right)+90=64$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a, x+8+90=64$

$\mathrm{Add\:the\:numbers:}\:8+90=98, x+98=64$

$\mathrm{Subtract\:}98\mathrm{\:from\:both\:sides}, x+98-98=64-98$

$\mathrm{Simplify}, x=-34$

$\mathrm{The\:Correct\:Answer\:is\:x=-34}$

$\mathrm{Hope\:This\:Helps!!!}$

Including a 6% sales tax, an inn charges $155.82 per night. Find the inn's nightly cost before tax is added.

Feliz [49]

we know the Inn is charging 155.82 and that's 100% plus 6%, namely 106% of an amout of say that is "x", being the 100%.

since we know that 155.82 is 106%, what is "x"?

$\begin{array}{ccll} amount&\%\\ \cline{1-2} 155.82&106\\ x&100 \end{array}\implies \cfrac{155.82}{x}=\cfrac{106}{100}\implies \cfrac{155.82}{x}=\cfrac{53}{50} \\\\\\ 7791=53x\implies \cfrac{7791}{53}=x\implies 147=x$

How do I find QS here?

juin [17]

Answer: 12.
To solve this problem, let's first solve for x. Thi is easiest done by figuring what QR is in terms of x using two equations, both from different lines.
In the first line: QR = 15 - 4x.
In the third line:QR = 13x - 1 - x = 12x - 1.
Now, we have to set these equations equal to each other. 15 - 4x = 12x - 115 = 16x - 116x = 16x = 1
Next, we take line three, 13x - 1, and substitute x as 1. The answer is 12.
