Answer:

$12

Step-by-step explanation:

The best way to do this is with a simple ratio. If you pay $3 for one meter, then for 4 meters, you’d pay $12. You BOUGHT 4 times more cord, which means you’d PAY 4 times more. Thus, 3 x 4 = 12!

Or with ratios:

1 meter : $3

multiplying both sides by 4

4 meters : $12

Answer:

Step-by-step explanation:

$8^{12}=3x-5\quad :\quad x=\frac{8^{12}+5}{3}\quad \left(\mathrm{Decimal}:\quad x=22906492247\right)$

$8^{12}=3x-5\\\\\mathrm{Add\:}5\mathrm{\:to\:both\:sides}\\3x-5+5=8^{12}+5\\Simplify\\\mathrm{Divide\:both\:sides\:by\:} 3\\\frac{3x}{3}=\frac{8^{12}}{3}+\frac{5}{3}\\\mathrm{Simplify}\\x=\frac{8^{12}+5}{3}$
