Answer:

1,875

Step-by-step explanation:

$\frac{2}{3}x-\frac{1}{5}x=x-1\\\\=> \frac{2.5}{15}x-\frac{3}{15}x=x-1 \\\\=> \frac{2.5-3}{15}x=x-1\\\\=> \frac{10-3}{15}x=x-1\\\\\frac{7}{15}x=x-1\\\\=> 7 x=15(x-1)\\\\ 7x=15x-15\\\\ 8x=15\\\\ x =\frac{15}{8}=1,875$

I'm not sure what the question is here. If an answer is communicative property, go with that. If it is asking for $\pi x 27$ , the answer is about 84.8230016469.

Calcula la longitud en YARDAS de

tatiyna

Answer:

Las longitudes solicitadas en yardas son:

Trayecto A = 109.361 yardas.
Trayecto B = 20.231785 yardas.

Step-by-step explanation:

Para hacer la conversión de unidades que requieres en el ejercicio, debes saber que:

1 metro = 1.09361 yardas

Con ese factor de conversión tú puedes hacer reglas de tres para calcular las medidas que requieres. En el caso del trayecto A:

Si:

1 metro = 1.09361 yardas
100 metros = X

Entonces:

$x=\frac{100m *1.09361yardas}{1m}$

Cancelamos metros y obtenemos:

x = 100 * 1.09361 yardas
x = 109.361 yardas

En este caso, el trayecto A en yardas corresponde a 109.361 yardas. El mismo procedimiento puede aplicarse para el trayecto B:

Si:

1 metro = 1.09361 yardas
18.50 metros = X

Entonces:

$x = \frac{18.50m*1.09361yardas}{1m}$

Cuando se cancelan los metros se obtiene:

x = 18.50 * 1.09361 yardas
x = 20.231785 yardas

Así, el trayecto B en yardas corresponde a 20.231785 yardas.
