Question

Write the word sentence as an inequality. Then solve the inequality.

The product of $-3$ and a number p is greater than $21$

Answer 1

Given : The product of $-3$and a number$p$ is greater than $21$

According to the given sentence the inequality is:

$\Rightarrow -3p>21$

$\Rightarrow \frac{-3p}{-3}<\frac{21}{-3}$ [ Divide both sides by $-3$ and reverse the sign of inequality ]
$\therefore p<-7$

Hence, the required solution of an inequality is $p<-7$
