Is that \[\frac{5}{10x^2} = \frac{1}{10x}\]?
Well, whatever it is, cross-multiplying should lead you to a solution.
\[5*10x = 1*10x^2\]Cancel any common factors and solve.
OpenStudy (anonymous):
yes that is the problem
OpenStudy (anonymous):
so would the answer be 4=x
OpenStudy (anonymous):
x=0 or 1/5
OpenStudy (anonymous):
no 4 is not it

i think its B.
OpenStudy (anonymous):
ok well thnx for ur help anyway, could u help me out with one more problem?
OpenStudy (anonymous):
you could use mathway its what ive been using most of High School.(:
OpenStudy (whpalmer4):
Come on, this is easy: after cross-multiplying, we have
\[5∗10x=1∗10x^2\]\[50x=10x^2\]Do you see any common factors on both sides of the equals sign?
OpenStudy (whpalmer4):
If not, why don't you try dividing both sides of the equation by \(x\) and tell me what you get?
