Rufina [12.5K]

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

Entify a pair of segments that are marked perpendicular to each other on
galina1969 [7]

Based on the image, FJH is perpendicular to JI as these two lines form a right angle.

<h3>What is a perpendicular line?</h3>

This name is given to a line that creates a right angle when it intersects or meets with another line.

This concept opposes the concept of parallel line, which is used to describe lines that never intersect and are always the same distance apart.

<h3>How do you identify a perpendicular line?</h3>
  1. Look for a right angle or a a 90° angles.
  2. Identify the lines that intersect to create this angle.
  3. Write down the two lines or line sections.

Based on the above, in the image given two lines that can be classified as perpendicular are the lines FJH (horizontal lines) and JI (vertical line) as their intersection creates a right angle.

HELP ASAP !!!! MATH LOVERS !!! A young chorus has 30 members. There are 14 boys in the chorus.
jolli1 [7]
So, 14 out of 30 of the members are boys. There are 14 boys in chorus. 16 girls. 

The ratio would be:

14:16

Now, divide both sides by two to simplify. 

14/2= 7

16/2= 8

7:8

"A" 7/8, 7:8 is the <em>answer
</em>
