Solve the problem by setting up and solving an appropriate inequality. 5 more than three times a number is greater than 20. Find all of the numbers that satisfy this relationship.
A) $( - \infty , 6 )$
B) $( - \infty , 5 )$
C) $( 6 , \infty )$
D) $( 5 , \infty )$

Quizplus · Accepted Answer

The inequality is $3x + 5 > 20$. Subtract 5 from both sides to get $3x > 15$. Divide both sides by 3 to get $x > 5$. Therefore, the solution is $(5, \infty)$.
