Answer:
x=16
y=40
Step-by-step explanation:
x + y = 56
y = 56 - x (isolate a variable)
y = -x + 56 (this is optional)
2x = .5y + 12
2x = .5(-x + 56) + 12 (substitute for y)
2x = -.5x + 28 + 12
2x = -.5x + 40
2.5x = 40
x = 16
16 + y = 56 (plug what you got for x back into the original eq)
y = 40
X = # of woodwind instruments
y = # of brass instruments
2x = y
150 = x + y
I hope this helps you!
Answer:
33.3%
Step-by-step explanation:
$2 on nachos and $2 on candy will get you $4 spent on them both.
You then have a fraction (4/12)which is 1/3.
1/3=33.3%
Ok so there is 60 minutes in an hour and you have 107 minutes so
107-60 = 47 ( 60 has become an hour)
So we are left with 47 minutes, so add the hour to 7:45 which will make it 8:45 pm
Then add 15 to make it 9:00 pm ( 47 - 15 = 32)
And so then add 32 minutes to 9:00 pm
Answer is 9:32 p.m.
