Valentina va de compras al mall con $50.000. Gasta 3/5 de esa cantidad en un buzo y la mitad del resto en una falda.¿cuanto dine
Vladimir [108]

Answer:

The amount left with Valentina is $10,000.

Step-by-step explanation:

The question is:

Valentina goes shopping at the mall with $50,000. She spends 3/5 of that amount on a diver and half the rest on a skirt. How much money does Valentina have left?

The original amount Valentina had was, <em>P</em> = $50,000.

Compute the amount spent on a diver as follows:

D = \frac{3}{5}th of $50,000

   =\frac{3}{5}\times 50000\\=30000

The amount spent on a diver was, <em>D</em> = $30,000.

Amount left:

A = P - D

   = 50000 - 30000

   = 20000

Compute the amount spent on a skirt as follows:

S = \frac{1}{2} of $20,000

  =\frac{1}{2}\times 20000\\=10000

Amount left:

A₁ =  A - S

   = 20000 - 10000

   = 10000

Thus, the amount left with Valentina is $10,000.

Solve this quadratic equation by completing the square. x^2+4x=15
AlekseyPX

Answer:

x =  -2  ±sqrt( 19)

Step-by-step explanation:

x^2 + 4x = 15

Take the coefficient of x

4

Divide by 2

4/2 =2

Square it

2^2 = 4

Add it to each side

x^2 + 4x+4 = 15+4

(x+2)^2 = 19

Take the square root of each side

sqrt( (x+2)^2) =±sqrt( 19)

x+2 =  ±sqrt( 19)

Subtract 2 from each side

x+2-2 = -2  ±sqrt( 19)

x =  -2  ±sqrt( 19)
