Eddie the elf made 13 toys one day in the workshop. some were dolls and the rest were action figures. the number of action figur
Lunna [17]
To solve this problem we first call x = number of action figures, y = number of dolles. A system of two equations with two unknowns must be made to describe the problem. The system is the following:
 (x + 1) + y = 13
 1/2 * x = y.
 Then solving the system we have that x = 8 and y = 4.
 Since we know that the number of action figures is twice as many dolls plus one, then x = 8 + 1 = 9.
 Thus,
 dollos = 4
 action figures = 9

recall that a cube has all equal sides, check the picture below.


\bf \textit{volume of a cube}\\\\
V=x^3~~
\begin{cases}
x=side's~length\\[-0.5em]
\hrulefill\\
V=5.12
\end{cases}\implies 5.12=x^3
\\\\\\
\sqrt[3]{5.12}=x\implies 1.72354775\approx x
