cross multiply
8.5x=520
x= 61.18 grams
hope this helps
we know that
a piece of cable [tex]8.5[/tex] cm long weighs [tex]52[/tex] grams
so
by proportion
[tex]\frac{52}{8.5}\frac{grams}{cm}=\frac{x}{10}\frac{grams}{cm} \\ \\8.5*x=10*52\\ \\x=(10*52/)8.5\\ \\x=61.18\ grams[/tex]
therefore
the answer is
[tex]61.18\ grams[/tex]
