Answer:
Step-by-step explanation:
For finding the system of equations you can use one of two methods. There's the elimination method and also the substitution method. For this I think the best way we could go at solving this is by using the elimination method. Since we can eliminate the 2y. We can then solve for x and then we'll go from there.
Now that we know what x is we can substitute it for one of the equations and then we will be able to solve for y.
So now we have the x and the y and once we place them together we can get the solution of those two equations, and the solution is .
Answer:
5250 g
Step-by-step explanation:
Given : Density of liquid is 1.50 g/ml
Volume of liquid is 3.50 liters
Solution :
Since 1 liter = 1000 ml
So, Volume of liquid is 3.50 liters = 3.5*1000 = 3500 ml.
Now
Hence , the mass of the liquid is 5250 g.
