Paul has completed 140 laps so far this season. He completes an additional 12 laps during each practice. Jacklyn has completed 5
kakasveta [241]

Paul: 140 + 12x

Jacklyn: 56 + 16x

Where x is how many practice sessions he had this season

"After how many more practices will Paul and Jacklyn have completed the same number of laps?"

This means what will x be if both equations are equal to each other

140 + 12x = 56 + 16x

Isolate x in one side by subtracting both sides by 12x

140 + 12x - 12x = 56 + 16x - 12x

140 = 56 + 4x

Subtract both sides by 56 to shift the 56 from the right side to the left side

140 - 56 = 56 - 56 + 4x

84 = 4x

Divide both sides by 4 to isolate x

84/4 = 4/4x

21 = x

x = 21

They'll have completed the same number of laps after 21 practices

Hope it helps :)

Giren: Lines a and b <br> Are perpendicular.<br> Prove: &lt;3 and &lt;4 are complementary.
Nikolay [14]
Since lines a and b are perpendicular, that means it is a right angles so angles a+b=90 so they are complementary

. 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>
