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.
