Usando proporciones y regla de três, tiene-se que cada pizza le costó $58.33.

  • Para encontrar el precio de cada pizza, usa-se proporciones, aplicando una regla de três.
  • A medida que aumenta la cantidad, también lo hace el precio, por lo que las medidas son directamente proporcionales y se aplica la multiplicación cruzada.
  • $350 por 6 pizzas.  ¿cuánto por 1?

La regla de três es:

$350 - 6 pizzas

x - 1 pizzas

Aplicando multiplicación cruzada:

6x = 350

x = \frac{350}{6}

x = 58.33

Un problema similar, que tambíem involucra proporciones, es dado en brainly.com/question/24617308

Rudik [331]
<h2>Answer:</h2>

f^{-1}  (x)=\sqrt{\frac{x}{14}}.

<h2>Step-by-step explanation:</h2>

<h3>1. Write the expression.</h3>

y=14x^2

<h3>2. Substitute y for x, and x for y.</h3>

x=14y^{2}

<h3>3. Solve for y.</h3>

14y^{2}=x\\ \\y^{2} =\frac{x}{14} \\ \\y=\sqrt{\frac{x}{14}}

<h3>4. Express your result.</h3>

f^{-1}  (x)=\sqrt{\frac{x}{14}}.
