You just have to add. Ex AC you would add them and see if it's the same if you add DF
Answer:
No solution
Step-by-step explanation:
3 x + y = 4 (1)
− 3 x − y = − 8 (2)
Add (1) and (2)
0 + 0 = -4
0 = -4 is a false statement
So, no solution
Answer:
Approximately 4.58 minutes.
Step-by-step explanation:
The diameter of hose is in centimeters, that is 2.9 cm.
Velocity is in m/s that can be converted into cm/s.
Let the velocity be 'v'.
v = 3.3 m/s= 330 cm/s
The amount of water following through the cross sectional area of the hose is.
diameter = 2.9 cm
The cross sectional are of the hose is approximately . To volume of water that flows through the hose each second, multiply its velocity by the cross sectional area of the hose.
Volume/ second =
This is approximately . There are in one liter.
Total volume
To determine the time in seconds, divide the total volume by the volume per second.
t =
This is roughly 275 seconds.
We can convert 275 seconds into minutes.
t (mins) = minutes.
So it will take 4.58 minutes to fill the wading pool.
Answer:
-3 = n
Step-by-step explanation:
11(n − 1) + 35 = 3n
Distribute
11n -11 +35 = 3n
Combine like terms
11n +24 = 3n
Subtract 11n from each side
11n -11n +24 = 3n -11
24 = -8n
Divide by -8
24/-8 = -8n/-8
-3 = n
The answer for this question is N=-48 because you divid the numbers
