Solve the following inequality. -9/20a-5>4

OpenStudy (anonymous):

First, we must normalize it. $-\frac{9}{20}a - 5 >4$ We want to solve for the variable, i.e. $a$... so let's put it in terms of the variable. Add 5 to both sides. $-\frac{9}{20}a > 9$ Now, let's divide both sides by $-\frac{9}{20}$ or, equivalently, multiply by $-\frac{20}{9}$ So, see as follows. Note that when multiplying by -1, we need to take care of flipping the equivalence relation. $a < -20$
