The value of r of the given equation is 3. option B
Step-by-step explanation:
Given,
[tex]\frac{1}{4} (r-\frac{5}{2} ) = \frac{1}{8}[/tex]
or, [tex]r - \frac{5}{2} =(\frac{\frac{1}{8} }{\frac{1}{4} })[/tex] [ [tex]\frac{1}{4}[/tex] will be dividing by [tex]\frac{1}{8}[/tex]]
or, [tex]r-\frac{5}{2}= \frac{1X4}{8X1}[/tex]
or, [tex]r-\frac{5}{2} = \frac{1}{2}[/tex]
or, r = [tex]\frac{1}{2} +\frac{5}{2}[/tex]
or, r = [tex]\frac{6}{2}[/tex]
or, r = 3
Hence the value of r is 3.
