Answer
$\frac{1}{x}$ - 10 $\gt$ 0
Work Step by Step
"10 subtracted from" translates as:
something - 10
i.e. If I had "10 subtracted from" 20... it would translate as
20 - 10
"the reciprocal of x"
$\frac{1}{x}$
Combining those two 'components:'
$\frac{1}{x}$ - 10
"Is greater than" translates to the symbol $\gt$
SO
$\frac{1}{x}$ - 10 $\gt$ 0
