Answer:

El reloj está marcando:

las 4:00 horas

Step-by-step explanation:

El reloj avanzó a su mismo ritmo pero en sentido contrario a partir de las 6:45

si ahora son las 9:30 el reloj marca:

9:30 = 9horas 30minutos = 9h 30'

6:45 = 6horas 45minutos = 6h 45´

1 hora = 60'

9h 30' = 8h + 60' + 30' = 8h + 90' = 8h 90'

entonces:

 8h 90'

- 6h 45'

= 2h 45

entonces el reloj está marcando 2h 45' menos que la hora en que se dañó.

por tanto:

 6h 45'

- 2h 45'

= 4h 00'

El reloj ahora está marcando las

4 horas en punto.

A printer prints an average of 200 1/2 pages per hour approximately how many pages did it print in an 8 hour period
Vika [28.1K]

Answer:

1,604 pages

Step-by-step explanation:

Let’s make a proportion

The printer prints 200 1/2, or 200.5 pages per hour, and prints x pages per 8 hours

200.5/1=x/8

Cross multiply

1*x=200.5*8

x= 1604

So, the printer prints 1,604 pages in & hours

The sum of two numbers is 46​, and the difference between the numbers is 4. Find the numbers.
Oduvanchick [21]
X+y = 46 so x = 46 - y
x-y = 4

substitute x = 46 - y into x-y = 4

x-y = 4
46 - y -y = 4
2y = 42
y = 21

x - y = 4
x - 21 = 4
x = 25

answer
the numbers are 21 and 25

double check
25 + 21 = 46
25 - 21 = 4
