Answer:
360 hours
Step-by-step explanation:
When trying to find the number of hours out of the number of days someone has been doing something, assuming that she spent all 15 days traveling with no rest, you just multiply however many days (In this case, 15 days) by 24 hours.
This gives us the equation 15 times 24, which then equals 360.
A way I check these is that I divide however many hours I got by 24 and make sure it equals our first number.
We get the equation 360 divided by 24, which does, in fact, equal 15.
Answer:
The solution is
Step-by-step explanation:
You are given the system of three equations:
Multiply the first equation by 4, the second equation by 3 and subtract them. Then multiply the third equation by 2 and subtract it from the second equation:
So,
Multiply the third equation by 23 and subtract it from the second equation:
Hence,
Substitute it into the second equation:
Substitute them into the first equation:
The solution is
