Multiple Choice

Solve each of the inequalities and express the solution sets in interval notation. Match each of the inequalities with the interval to obtain a true statement.
- $( - \infty , 18 ]$

A) $\frac { x + 4 } { 22 } - \frac { x + 9 } { 9 } \geq \frac { 7 } { 18 }$
B) $\frac { x - 5 } { 20 } - \frac { x - 2 } { 25 } \leq \frac { 1 } { 100 }$
C) $\frac { 6 x - 5 } { 10 } - \frac { x - 1 } { 20 } < - 4$
