cuanto pagaríamos por un libro cuyo precio es de $25 si le aplicamos un descuento del 25% cuanto dinero ahorramos

kotegsom [21]

Tenemos precio de lista de $25 para el libro.

Si aplicamos un descuento del 25%, este descuento representa:

$D=(\frac{25}{100})\cdot25=0.25\cdot25=6.25$

Ahorramos $6.25.

El precio que pagamos el libro es $18.75.

$P=L-D=25-6.25=18.75$

What is the solution to the equation?

Gelneren [198K]

Answer:

Hello,

answer B

Step-by-step explanation:

$\dfrac{2}{x} -\dfrac{x}{x+5} =\dfrac{10}{x^2+5x} \\\\we\ suppose\ x\neq 0\ and\ x\neq -5\\\\\text{Reducing to the same denominator}\\\dfrac{2(x+5)-x^2}{x(x+5)} =\dfrac{10}{x^2+5x} \\\\Simplify\ by\ x^2+5x\\\\2x+10-x^2=10\\\\-x^2+2x=0\\\\-x(x-2)=0\\\\roots\ are\ 2 \ and\ 0\ (to\ be\ excluded)\\\\Root=2\\$
