Si Martha retira de su cuenta el 10% para los transportes del mes. ¿Cuál es el nuevo saldo de la cuenta?
notsponge [240]

Respuesta:

0,9 veces

Explicación paso a paso:

Deje que la cantidad en la cuenta de Martha se denote como x, que es la cantidad en la cuenta = x

Porcentaje retirado para transporte = 10%

El porcentaje total siempre será del 100%

Por lo tanto, si se retira el 10%, entonces; el porcentaje restante es:

Porcentaje total: porcentaje gastado en transporte

(100% - 10%) * monto en cuenta

90% * x = 0,9 * x = 0,9x

Saldo de cuenta nueva = 0.9x

Answer:

\boxed{\sf Option \ 4}

Step-by-step explanation:

\sqrt{2x-3} +x=3

Subtract x from both sides.

\sqrt{2x-3} +x-x=-x+3

\sqrt{2x-3}=-x+3

Square both sides.

( \sqrt{2x-3})^2 =(-x+3)^2

2x-3=x^2-6x+9

Subtract x²-6x+9 from both sides.

2x-3-(x^2-6x+9 )=x^2-6x+9-(x^2-6x+9)

-x^2 +8x-12=0

Factor left side of the equation.

(-x+2)(x-6)=0

Set factors equal to 0.

-x+2=0\\-x=-2\\x=2

x-6=0\\x=6

Check if the solutions are extraneous or not.

Plug x as 2.

\sqrt{2(2)-3} +2=3\\ \sqrt{4-3} +2=3\\\sqrt{1} +2=3\\3=3

x = 2 works in the equation.

Plug x as 6.

\sqrt{2(6)-3} +6=3\\ \sqrt{12-3} +6=3\\\sqrt{9} +6=3\\3+6=3\\9=3

x = 6 does not work in the equation.
