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

1.    An AP has a common difference of 3.  Given that the nth term is 32, and the sum of the first n terms is 185, calculate the
netineya [11]

Answer:

The value of n is 10

Step-by-step explanation:

The formula of the nth term of the arithmetic progression is a_{n} = a + (n - 1)d

  • a is the first term
  • d is the common difference between each 2 consecutive terms
  • n is the position of the term

The formula of the sum of nth terms is S_{n} = \frac{n}{2} [2a + (n - 1)d]

∵ An AP has a common difference of 3

∴ d = 3

∵ The nth term is 32

∴ a_{n} = 32

→ Substitute them in the 1st rule above

∵ 32 = a + (n - 1)3

∴ 32 = a + 3(n) - 3(1)

∴ 32 = a + 3n - 3

→ Add 3 to both sides

∴ 35 = a + 3n

→ Switch the two sides

∴ a + 3n = 35

→ Subtract 3n from both sides

∴ a = 35 - 3n ⇒ (1)

∵ The sum of the first n terms is 185

∴ S_{n} = 185

→ Substitute the value of S_{n} and d in the 2nd rule above

∵ 185 = \frac{n}{2} [ 2a + (n - 1)3]

∴ 185 = \frac{n}{2} [2a + 3(n) - 3(1)]

∴ 185 = \frac{n}{2} [2a + 3n - 3]

→ Multiply both sides by 2

∴ 370 = n(2a + 3n - 3)

∴ 370 = 2an + 3n² - 3n

→ Substitute a by equation (1)

∴ 370 = 2n(35 - 3n) + 3n² - 3n

∴ 370 = 70n - 6n²+ 3n² - 3n

→ Add the like terms in the right side

∵ 370 = -3n² + 67n

→ Add 3n² to both sides

∴ 3n² + 370 = 67n

→ Subtract 67 from both sides

∴ 3n² - 67n + 370 = 0

→ Use your calculator to find n

∴ n = 10 and n = 37/3

∵ n must be a positive integer ⇒ 37/3 neglecting

∴ n = 10

∴ The value of n is 10

What is the value of X?
zepelin [54]
The 3 inside angles of a triangle need to equal 180 degrees.

 The angle below the 100 degrees would be 180-100 = 80 degrees.

Now you have 80 and 70, which equals 150 degrees.

 Angle X = 180 -150 = 30 degrees

How do how you cross cancel multiplying fractions
DENIUS [597]

It's easy once you spot the ones that can cross cancel!

Say we have the fractions 8/10 and 20/23. \frac{8}{10} \frac{20}{23} (it's easier to see on top of each other)

If you look diagonally , so 8 and 23 and 10 and 20, you can see that 10 and 20 have a common factor. So we divide it by the highest common factor to reduce those numbers, making it easier to multiply. 10 and 20 can become 1 and 2, dividing by 10. So now we are left with 8/1 and 2/23, and now we multiply normally going across so 16/23.

This works going both diagonals and simplifying both, but in that case it would be easier to try and simplify the fractions before cross multiplying them.

Basically: look for those diagonals and if they can be divided down by the highest common factor, go for it to make it easier to multiply normally afterwards.

Hope I helped!
