Una empresa comercial vende automóviles cuyo precio es de S/. 60 000, con una cuota inicial del 20%, para cancelar el saldo en 3
Inessa05 [86]

Responder:

2560

Explicación paso a paso:

Dado lo siguiente:

Precio del automóvil = 60000

Cuota inicial = 20% del precio = (0.2 * 60000 = 12,000

Saldo = (60000 - 12000) = 48000

La empresa cobra un interés simple del 12% cada 6 meses

Periodo de pago = 30 meses / 6 = 5 periodos

Interés simple: p * r * t

= 48000 * 0,12 * 5 = 28800

Por lo tanto, monto total a reembolsar, incluidos los intereses:

Balance + 28800; 48000 + 28800 = 76800

El reembolso mensual es fijo;

Por lo tanto,

76800/30 = 2560

VashaNatasha [74]

Answer:

37 birdhouses

Step-by-step explanation:

Given:

It takes 1/3 pint of paint to cover a birdhouse.

There are 12 1/3 pints of paint in a can.

Question asked:

Write and evaluate a division expression to find the number of bread houses that can be painted.

Solution:

<em><u>We will solve it by unitary method:</u></em>

By using \frac{1}{3} pints of paint, we can paint = 1 birdhouse

By using 1 pints of paint, we can paint = \frac{1}{\frac{1}{3} }=1\times3=3\ birdhouses

By using  12\frac{1}{3} pints of paint, we can paint =3\times12\frac{1}{3}

                                                                   =3\times\frac{12\times3+1}{3} \\\\ =3\times\frac{37}{3} \\ \\ =3\ canceled \ by\ 3\\=37\ birdhouses

Thus, 37 birdhouses can be painted by using 12\frac{1}{3} pints of paints.

Please someone help and thank you
Allisa [31]

Answer:

x = 3

Step-by-step explanation:

4(x+3) - x = x + 18

4x + 12 - x = x + 18

3x + 12 = x + 18

3x - x + 12 = x - x + 18

2x + 12 = 18

2x + 12 - 12 = 18 - 12

2x = 6

2x/2 = 6/2

x = 3
