Step-by-step explanation:
we can use it to solve age problems and Money problems e.t.c
To answer this item, let x be the amount of water. The concentration (in % sugar) of the solution is calculated by dividing the amount of sugar by the total amount. That is,
C = (S/ (S + x))(100%)
Substituting the known values to the equation,
75 = ((0.5/(0.5 + x))(100%)
The value of x from the equation is 0.167.
<em>Answer: 0.167 lbs of water</em>
You know that the interior angles of a triangle equal 180 degrees, and you know that two of the angles are 90 and 42. Do 180-90-42, and the last angle is 48.
6 x n or 6n, I'm pretty sure.
