Answer:
x=−2 and y=−1
Step-by-step explanation:
Sorry if it is too confusing
Well, we can use some simple addition, okay? So if Ally has 7 cubes, and Greg has four, we can use the equation: x+y = ?, so 7 + 4 = 11. x and y don't mean anything in this scenario, but I just used them as variables. I hope this helps! :)
The water flows 6 liters per minute in the other branch of pipe.
Step-by-step explanation:
Given,
Flow of water in main pipe = 10L/min
Flow of water in one branch = 4L/min
Flow of water in other branch = x
Flow of water in main pipe = Flow in one branch + Flow in other branch
The water flows 6 liters per minute in the other branch of pipe.
