Answer:

hay 10 billetes de 2000

hay 4 billetes de 5000

Step-by-step explanation:

Planteamos las siguientes ecuaciones...:

x= billetes de 2000

y= billetes de 5000

ecuaciones :

1)    x+y = 14

2)  2000x + 5000y =40000

despejamos primera ecuacion y remplazamos en segunda  :

1) x= 14-y

2)  2000(14-y)  +  5000y  =  40000

    28000- 2000y+5000y  = 40000

                           3000y=  40000 - 28000

                                  y= 4

reemplazamos este valor en primera ecuacion:

x+y = 14

 x+ 4= 14

    x= 10

ahora reemplazamo valor de X       y      valor de Y

2000(10)   + 5000(4)  =40000

                  40000    =40000                        

hay 10 billetes de 2000

hay 4 billetes de 5000

Espero que esto te ayude

The weight of oranges growing in an orchard is normally distributed with a mean weight of 6.5 oz. and a standard deviation of 1.
sergey [27]
Add 3 standard deviations above and below the mean to get the range in which 99.7% of the data in a normal distribution will fall
6.5 + 4.5 = 11
6.5 - 4.5 = 2
So 2 to 11 ounces would be the interval

Lily is a lilypad in a small pond. Lily doubles in size each day. On the 20th day she covers the whole pond. On what day was Lil
svetoff [14.1K]

Answer:

19th day

Step-by-step explanation:

So say Lily was 1 when Lily was planted

First day Lily is 2

Second day Lily is 4

Third day Lily is 8

etc...

See the pattern?

The pattern is 2^x

On the 20th day, Lily was 2^20

So when Lily was half, Lily was 2^20 / 2

2^x = 2^20 / 2

2^x = 2^19

On the 19th day, Lily was half.

-4k + 2(5k − 6) = −3k – 48
nalin [4]

Answer:

k = -4

Step-by-step explanation:

-4k + 2(5k − 6) = −3k – 48

Distribute on the left side.

-4k + 10k - 12 = -3k - 48

Combine like terms on the left side.

6k - 12 = -3k - 48

Add 3k to both sides.

9k - 12 = -48

Add 12 to both sides.

9k = -36

Divide both sides by 9.

k = -4
