Answer:

n = 20

Step-by-step explanation:

4n + 14 - 5n = -6

(4n - 5n) + 14 = -6      Combine like terms

-n + 14 = -6

    -14    -14                Subtract 14 from both sides

-n = -20

/-1    /-1                        Divide by -1

n = 20

Answer:

n = 20

Step-by-step explanation:

4n+14-5n=-6

So we have to simplify the equation.

4n + -5n = -n

So our equation looks like this now -> -n+14=-6.

So now to get -n by itself we get 14 and -6 by itself.

So we do -6 - 14 and we get -20.

So our equation looks like -n=-20.

So now we have to make n positive we do -n ÷ -1 which is n.

And since we divided -n by -1 we have to divide -20 by -1 which is 20.

So n is 20.

El peso que cargan tres pick-ups están en la razón de 2:6:7, cuánto carga el pick-up más grande, si el pick up menor carga 1500k
skad [1K]

Utilizando proporciones, hay que el pick-up más grande carga 5250 kg.

  • Este problema se resuelve por proporciones, por médio de una regla de três.

El peso que cargan tres pick-ups están en la razón de 2:6:7

  • 2 + 6 + 7 = 15.
  • O sea, el pick-up menor carga \frac{2}{15} de el total, que es equivalente a 1500 kg.
  • El pick-up más grande carga \frac{7}{15} de el total, que es equivalente a x kg.

La regla de três es:

\frac{2}{15} - 1500 kg

\frac{7}{15} - x kg

Aplicando multiplicación cruzada:

\frac{2x}{15} = \frac{1500(7)}{15}

2x = 1500(7)

x = \frac{1500(7)}{2}

x = 5250

El pick-up más grande carga 5250 kg.
