Question 550898

{{{7-10z>5}}} Start with the given inequality.



{{{-10z>5-7}}} Subtract {{{7}}} from both sides.



{{{-10z>-2}}} Combine like terms on the right side.



{{{z<(-2)/(-10)}}} Divide both sides by {{{-10}}} to isolate {{{z}}}. note: Remember, the inequality sign flips when we divide both sides by a negative number. 



{{{z<1/5}}} Reduce.

Answer:


So the solution is {{{z<1/5}}} 



Which in decimal form is {{{z<0.2}}}
