Answer:
Subtract the hours to get 12-3 = 9
Or you could start at 3 PM, and count your way up one hour at a time, until you get to 12 AM. You should count out 9 hours in total.
An alternative is you could note from 3 PM to 3 AM is a span of 12 hours. Take 3 hours away from 3 AM, and you'll rewind the clock back to 12 AM. So 12-3 = 9. :-)

Step-by-step explanation:
Answer:
x=-15, y=25. (-15, 25).
Step-by-step explanation:
2x+3y=45
x+y=10
--------------
x=10-y
2(10-y)+3y=45
20-2y+3y=45
20+y=45
y=45-20
y=25
x+25=10
x=10-25
x=-15

Answer:
12.4
Step-by-step explanation:
The distance between (7,21) and (-5,18)
d =sqrt( (-5-7)^2 + (18-21)^2)
= sqrt(( -12)^2 + (-3)^2)
= sqrt(144+9)
= sqrt(153)
=12.36931688
To the nearest tenth
12.4
Your answer is 0.0909090909 if I'm not mistaken.
