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 have 4 green picks and, after adding some orange picks, you know that every 2 picks from 3 are orange.
So, 1 green pick needs 2 orange picks, three in total. Since you have 4 green picks, then you will have in total 3·4=12 picks (4 green and 12-4=8 orange).
Answer: there are 12 picks in total.
A.
To solve, you need to get the variable by itself.
Order of operations:
Square root both sides.
(x-5)= plus/minus root 3, as 3 is not a perfect square.
Now you need to add 5 to both sides to get it to disappear on the side with the x.
x=root3 +or - 5, which can be rearranged so that 5 is the first term.
