Respuesta :
21r<7
First you divide 21 from both sides
Note= becuz it is not a negative, you do not flip the sign*
21r/21<7/21
r<1/3
First you divide 21 from both sides
Note= becuz it is not a negative, you do not flip the sign*
21r/21<7/21
r<1/3
The solution of the inequality is: [tex]r < \frac{1}{3}[/tex]
Given the inequality:
[tex]21r<7[/tex]
Solve for r as algebra as follows:
Divide both sides by 21
[tex]\frac{21r}{21} <\frac{7}{21}\\r < \frac{7}{21}[/tex](division property of equality)
Simplify
[tex]r < \frac{1}{3}[/tex]
