In complete sentences, explain whether or not it makes sense to say that the density of helium is 0.1785 kilograms per square me
2 answers:
Answer:
No
Step-by-step explanation:
No, it does not make any sense to say that the density of helium is 0.1785 kilograms per square meter because because density of helium, and all the rest of the chemicals, are calculated by unit mass per unit volume as the density is given as:
where mass is measured in kilograms and volume is measured in cubic meter.
Thus, the density of the helium will be that is 0.1785 kilograms per cubic meter.

Answer:
Step-by-step explanation:
The given system is:
Since I prefer to use smaller numbers I'm going to divide both sides of the first equation by 3 and both sides of the equation equation by 6.
This gives me the system:
We could solve the first equation for and replace the second
with that.
Let's do that.
Subtract on both sides:
So we are replacing the second in the second equation with
which gives us:
Now recall the first equation we arranged so that was the subject. I'm referring to
.
We can now find given that
using the equation
.
Let's do that.
with
:
So the solution is (8,-1).
We can check this point by plugging it into both equations.
If both equations render true for that point, then we have verify the solution.
Let's try it.
with
:
is a true equation so the "solution" looks promising still.
with
:
is also true so the solution has been verified since both equations render true for that point.
