. Two planes are 1620 miles apart and are traveling toward each other. One plane is traveling 120 mph
Nadusha1986 [10]

Answer:

Step-by-step explanation:

let the speed of one plane=x mph

speed of other plane=x+120 mph

x×1.5+(x+120)×1.5=1620

(x+x+120)×1.5=1620

(2x+120)×1.5=1620

3x+180=1620

3x=1620-180

3x=1440

x=480

speed of one plane=480 mph

speed of second plane=480+120=600 mph

Roberto tiene 20 balones entre azules y rojos el tiene mas balones rojo que azules y los guarda en cuatro bolsas que contienen l
Anuta_ua [19.1K]

Se pueden concluir dos posibilidades para cada bolsa y toda la colección:

  1. 4 balones rojos y un balón azul, lo cual lleva a 16 balones rojos y 4 balones azules.
  2. 3 balones rojos y dos balones azules, lo cual lleva a 12 balones rojos y 8 balones azules.

<h3>¿Cuántos balones rojos tiene Roberto en las cuatro bolsas?</h3>

En este problema conocemos que Roberto tiene 20 balones entre azules y rojos y que existen más balones rojos que azules. Puesto que los balones son objetos que pueden contarse, los datos a buscar deben ser números enteros y positivos y que están distribuidos equitativamente en cuatro bolsas. Entonces las cantidades de balones por bolsa son:

x = 20 / 4

x = 5

Existen 5 balones por bolsa y bajo la consideración de que existen balones azules, que cada bolsa tienen la misma proporción de balones rojos a azules y que los balones rojos son más que los balones azules, se pueden concluir dos posibilidades para cada bolsa:

  1. 4 balones rojos y un balón azul, lo cual lleva a 16 balones rojos y 4 balones azules.
  2. 3 balones rojos y dos balones azules, lo cual lleva a 12 balones rojos y 8 balones azules.
