What is the difference of 8 times a number r and 12?

lapo4ka [179]

Answer:

The difference of 8 times a number r and 12 is solved for a number r and is given by $r=\frac{3}{2}$

Step-by-step explanation:

Given problem is the difference of 8 times a number r and 12

It can be written as

$(8\times r)-12$

To simplify the above expression :

8r-12

$8r-12=0$

$8r-12+12=0+12$ ( using addition property of equality )

$8r=12$

$8r(\frac{1}{8})=12(\frac{1}{8})$ (using division property of equality )

$r=\frac{3}{2}$

Therefore $r=\frac{3}{2}$

Therefore the difference of 8 times a number r and 12 is solved for a number r and is given by $r=\frac{3}{2}$
