Solve: -6 (-2)÷4(-3)

Mathematics
1 answer:
Katen [24]3 years ago
6 0

Answer:

-9

Step-by-step explanation:

Simplify the following:

-6×(-2)/4 (-3)

-6×(-2)/4 (-3) = (-6 (-2) (-3))/4:

(-6 (-2) (-3))/4

The gcd of -2 and 4 is 2, so (-6 (-2) (-3))/4 = (-6 (2 (-1)) (-3))/(2×2) = 2/2×(-6 (-1) (-3))/2 = (-6 (-1) (-3))/2:

(-6-1 (-3))/2

(-6)/2 = (2 (-3))/2 = -3:

--3 (-3)

-3 (-1) = 3:

3 (-3)

3 (-3) = -9:

Answer: -9

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.

= -6<br> -2x + y<br> -x+3y<br> = -6
alexgriva [62]

Answer: x = 2.4 or 12/5, y = -1.2

Step-by-step explanation:

-2x + y = -6

=> y = 2x - 6

-x + 3y = -6

=> -x + 3(2x - 6)  = -6

=> -x + 6x - 18 = -6

=> 5x = 12

=> x = 12/5 or 2.4

-x + 3y = -6

=> - (2.4) + 3y = -6

=> 3y = -6 + 2.4

=> 3y = -3.6

=> y = - 1.2
