Answer:
b = 26.97 or b = 0.03
Step-by-step explanation:
[tex]\frac{\frac{4}{5} }{b} +b=27[/tex]
[tex]\frac{4}{5b} +b=27[/tex]
[tex]\frac{4+5b^{2} }{5b} =27[/tex]
[tex]4+5b^{2} =135b[/tex]
[tex]5b^{2} -135b+4=0[/tex]
[tex]b=\frac{135+\sqrt{18225-80} }{10}[/tex] or
[tex]b=\frac{135-\sqrt{18225-80} }{10}[/tex]
b = 26.97 or b = 0.03
