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

(sorry for sloppy/etc writing haha, it's hard with a mouse lol)
The answer is 183 and the is 123 and 194 and 823
He has walked 23 miles.
To solve this, you simply need to add all of the distances together.
4 + 4 + 7 + 6 + 2 = 23
Answer:
The constant of porportionality is k = 12.5; the equation that describes the relationship is y = 12.5x.
Step-by-step explanation:
When you divide the miles by the hours, it's always 12.5, meaning that k must be 12.5.
If x is the hours and k is 12.5, the equation that describes the relationship is y = 12.5x.
