You can use logarithms:

Log9(27) which will give you the value of x

X= 1.5

$9^x=27\\\\(3^2)^x=3^3\\\\3^{2\cdot x}=3^3\\\\3^{2x}=3^3\iff 2x=3\ \ \ /:2\Rightarrow x=1.5$

Tim has read 10% of a book. He has 45 more pages to finish. How many pages are there in the book?

Monica [59]

if Tim has read 10% of the book, that means he still hasn't read 90% of it yet, and we know that that 90% is 45 pages, so say the book has a total amount of pages of "x", which is 100%.

$\begin{array}{ccll} pages&\%\\ \cline{1-2} 45&90\\ x&100 \end{array}\implies \cfrac{45}{x}=\cfrac{90}{100}\implies \cfrac{45}{x}=\cfrac{9}{10} \\\\\\ 450=9x\implies \cfrac{450}{9}=x\implies 50=x$
