Write the product of the reciprocal of 5 and 5g-20

Sagot :

Answer:

[tex]reciprocal \: of \: 5 = \frac{1}{5} \\ reciprocal \: of \: (5g - 20) = \frac{1}{5g - 20} \\ product \: of \: reciprocals = ( \frac{1}{5} )( \frac{1}{5g - 20 } ) \\ = \frac{1}{5(5g - 20)} \\ = \frac{1}{(25g - 100)} \\ divide \: by \: 25 \: on \: everything \: (optional) \\ = \frac{(1 \div 25)}{(25g \div 25) - (100 \div 25)} \\ = \frac{0.04}{g - 4} [/tex]
