So first thing you gotta do is multiply the first equation by 5. Your first equation will be
.
Since these two lines are the same line, they have infinite solutions.
Answer:
500 millilitres
Step-by-step explanation:
Mass = Concentration x Volume
This rearranged gives:
Volume = Mass / Concentration
= 150 / 0.3 = 500 millilitres
Yes the simplified answer would be 1/9
Answer:

Step-by-step explanation:
Note that
.
Aha! We see a path to the solution!
We now know that our equation is actually
.
We can divide both sides by
to get
.
By inspection or taking the logarithm base 2 of both sides, we see that
.
So, the answer is
and we're done!
