Answer:
-2y
Step-by-step explanation:
Let's simplify step-by-step.
x−y−(x+y)
Distribute the Negative Sign:
=x−y+−1(x+y)
=x+−y+−1x+−1y
=x+−y+−x+−y
Combine Like Terms:
=x+−y+−x+−y
=(x+−x)+(−y+−y)
=−2y
Answer:
Infinitely many solutions.
Step-by-step explanation:
3x-3y=6
-6x+6y=-12
------------------
2(3x-3y)=2(6)
-6x+6y=-12
-------------------
6x-6y=12
-6x+6y=-12
--------------------
0=0
Answer:
It's B
Step-by-step explanation:
Bruj life is so hard. like aragahah this boy has me head over heels and all i want is him. god why can’t he open his eyes. anyway since your only concern is "given that they play a sport", only the top row is involved (12 total). Of those, 2 play an instrument. P(I|S) = 2/12, or 1/6.
So to convert from leiters per minute to milileters per second
lieters=L
milileters=ml
minute=M
second=S
L/M=liters pre minute
ml/s=milileters per second
so to convert, just conver them seperately first
L=1000ml
M=60S
therefor
conversion factor for M to S=
M times 60S/1M=minutes
conversion factor from L to ml=
L times 1000ml/L
so basically to convert, just multiply the equations gotether
L/M times 1000ml/L times M/60s (we flipped the M to S equation since M is on the bottom) =L/M times 1000/60=L/M times 100/6=L/M times 50/3
if you have 50 liters per minute than
50/1 times 50/3=2500/3=833.33333 ml per second
