See below:
Step-by-step explanation:
We can first setup an equation by doing the following:

Whole proccess above!
If you would like an explanation, please let me know so.
Its basically algebra and it's mainly on how you interpret it!
Have a nice day!
X/-3 = 12 + x
x = -36 - 3x
4x = 36
x= = 9
The number is 9.
Answer/Step-by-step explanation:
Quotient is simply the ratio of the first numerator to the second numerator:
Let's
are two fractions in same terms.
Thus,
{Divided by a fraction is equal to multiplied by its reciprocal}
=
Quotient is simply the quotient of their numerators.
Example could be:



2 is first numerator and 3 is the second numerator.

We can write the following proportion between the milligram and milliliters:

Solving for x, we have

Intuitively, the original 1000mg/250ml solution tells us that the number of milliliters is one fourth of the number of milligrams.
So, if we want 700mg, we have one fourth of this value for the milliliters:
