With 5lbs of sugar syrup to get a 25% syrup you would need to add 15lbs of water
16 ounces in a pound.
100 divided by 16 = 6.25 pounds, or 6lb 4oz.
It is 225. Because you do the volume of one rectangular prism the equation is 15 x 3 x 3 which gives you 135. Then you do the volume of the other rectangular prism the equation is 10 x 3 x 3 which gives you 60. Then you add 135 + 90 that then gives you the total volume which is 225.
We have the following expression:
S = 6x ^ 2
We must clear x from the equation.
For this, we follow the following steps:
Step 1)
Pass 6 to divide:
S / 6 = x ^ 2
Step 2)
Square root on both sides:
+/- root (S / 6) = x
Step 3)
Multiply numerator and denominator by 6:
x = + / - root (6S / 6 * 6)
Step 4)
Rewrite expression:
x = + / - root (6S / 36)
Step 5)
Take root to denominator:
x = + / - (root (6S)) / 6
Answer:
x = + / - (root (6S)) / 6
