9514 1404 393

Answer:

  • a=50
  • b=45

Step-by-step explanation:

We can subtract the second equation from 4 times the first:

  4(a +b) -(4a +1.5b) = 4(95) -(267.5)

  2.5b = 112.5 . . . . . simplify

  b = 45 . . . . . . . . . . divide by 2.5

  a = 95 -b = 50 . . . find 'a'

The solution is (a, b) = (50, 45).

9. Convert 10,000 seconds into<br> hours
arlik [135]

Answer: 2.7777 hours

Step-by-step explanation: Here, we're asked to convert 10,000 seconds into hours.

Unfortunately, we don't have a conversion factor for seconds and hours. However, we know that 60 seconds = 1 minute and 60 minutes = 1 hour.

So we can convert 10,000 seconds into hours by using both of these conversion factors. Also, it's important to understand that when we go from a smaller unit, seconds, to a larger unit, hours, we divide.

So let's first convert 10,000 seconds into minutes by dividing 10,000 by the conversion factor, 60, to get 166.6666 minutes.

Next, we convert minutes to hours by dividing 166.6666 by the conversion factor, 60, to get 2.7777 hours.

So 10,000 seconds is approximately equal to 2.7777 hours.
