Fiona y sus amigas fueron a una tienda de batidos. Pidieron tres batidos de fresa y dos batidos de proteínas por un total de $ 2
jeka94

Answer:

Un batido de proteínas cuesta $ 5,25.

Step-by-step explanation:

El sistema de ecuaciones descrito al final del enunciado coincide con lo descrito al comienzo del mismo, de modo que podemos concentraron casi exclusivamente en la resolución del sistema en cuestión, la cual se describe a continuación:

Este es el sistema a resolver:

x + 4\cdot y = 25,50 (1)

3\cdot x + 2\cdot y = 24,00 (2)

Donde x es el coste de un batido de fresa y y corresponde al coste de un batido de proteínas:

1) Despejamos x en (1):

x = 25,50 - 4\cdot y

2) Eliminamos x en (2):

3\cdot (25,50 - 4\cdot y) + 2\cdot y = 24,00

76,50 - 12\cdot y +2\cdot y = 24,00

3) Simplificamos y despejamos y:

10\cdot y = 52,50

y = 5,25

Un batido de proteínas cuesta $ 5,25.

What’s Distribute -x(5x+2)
MaRussiya [10]

Answer:

-5x^2-2x

Step-by-step explanation:

When distributing, you multiply the term outside the brackets to all the terms in brackets.

If the term outside the bracket is negative, then when distributing/opening the brackets, the signs of the terms changes.

So in this prob. -x would multiply to both +5x and +2

-x*5x+-x*2

∴-5x^2-2x
