What is the solution
Umnica [9.8K]

-3x + y = 4

Solve for y

y = 3x + 4

Plug this y value into the other equation.

-9x + 5y = -1

-9x + 5(3x + 4) = -1

Distribute 5(3x + 4)

-9x + 15x + 20 = -1

Subtract 20 from both sides

-9x + 15x + 20 - 20 = -1 - 20

-9x + 15x = -21

Combine like terms

6x = -21

Divide both sides by 6

6/6 x = -21/6

1x = -21/6

x = -7/2

x = -3.5 or -7/2

Plug this value into an equation to solve for y.

-3(-3.5) + y = 4

10.5 + y = 4

Subtract both sides by 10.5

10.5 - 10.5 + y = 4 - 10.5

y = -6.5

Check this answer by plugging the value of x into the other equation.

-9(-3.5) + 5y = -1

31.5 + 5y = -1

Subtract both sides by 31.5

31.5 - 31.5 + 5y = -1 - 31.5

5y = -32.5

Divide both sides by 5

y = -6.5 or -13/2

Therefore the solution is ( -3.5 , -6.5 )

en una piscina caben 45,000 litros. cuanto tiempo tarda en llenarse mediante un grifo que le anade 15 litros por minuto?
Elanso [62]

El volumen de un recipiente es igual al volumen de agua que puede contener el recipiente.

Por lo tanto, se necesitan <em>3000 minutos</em> o <em>50 horas</em> para que la piscina se llene de agua del grifo.

  • El volumen de agua que puede contener una piscina: 45.000 litros

  • Tasa de agua que sale de un grifo: 15 litros por minuto

  • El tiempo que tardará en llenarse la piscina se calcula como:

Cruz multiplicar

45.000 litros x 1 minuto / 15 litros

= 3000 minutos

  • También puede convertir 3000 minutos en horas

60 minutos = 1 hora

3000 minutos =?

Cruz multiplicar

3000 minutos x 1 hora / 60 minutos

= 50 horas

Por lo tanto, se necesitan 3000 minutos o 50 horas para que la piscina se llene de agua del grifo.
