Answer:

(-3,-4)

Look at attached pictures for work and the text below for the explanation of the work. The brown numbers represent the step number it is.

Step-by-step explanation:

Start by getting either the x or y values in both equations the same number but opposite sign. Ex 16 and -16. I did x. Then add the equations eliminating one variable, in mine it was x, and the solve for the other variable, in mine it was y. Then plug that variable back into one of the two original equations and solve for the other variable, in mine I solved for x.

. El Pirata Barba Plata ha legado a la isla del Coral para buscar un tesoro. En el mapa pone que, desde la orila, debe recorer 3
zhuklara [117]

Answer:

Entonces, el Pirata Barba Plata recorrerá en total 455 m o 0.455 km desde la orilla hasta el tesoro.

Step-by-step explanation:

En primer lugar es conveniente expresar las unidades en metros, ya que se requiere que la distancia total recorrida se encuentre expresada en metros. Para eso debes realizar una conversion de unidades, teniendo en cuenta que 1 hm equivale a 100 m y 1 dam es igual a 10 m.

Entonces podes aplicar las siguientes reglas de tres:

  • Si 1 hm equivale a 100 m, 3,7 hm a cuántos m equivalen?

m=\frac{3,7 hm*100m}{1 hm}

m= 370

Entonces 3,7 hm es igual a 370 m

  • Si 1 dam equivale a 10 m, 8,5 dam a cuántos m equivalen?

m=\frac{8,5dam*10m}{1 dam}

m= 85

Entonces 8,5 dam es igual a 85 m.

Para conocer la distancia que se recorrerá en total desde la orilla hasta el tesoro debes sumar la distancia que se recorre desde la orilla hacia el centro de la isla y la distancia que se recorre dando volteretas en la misma dirección. Esto es:

370 m + 85 m= 455 m

Por último, se aplica la siguiente regla de tres:

Si 1 m equivale a 0.001 m, 455  m a cuántos km equivalen?

km=\frac{455 m*0,001 km}{1 m}

km= 0.455

<u><em>Entonces, el Pirata Barba Plata recorrerá en total 455 m o 0.455 km desde la orilla hasta el tesoro.</em></u>
