Let's solve your equation step-by-step.
6.75+38x=1314
Step 1: Simplify both sides of the equation.
38x+6.75=534
Step 2: Subtract 6.75 from both sides.
38x+6.75−6.75=534−6.75
38x=132
Step 3: Multiply both sides by 8/3.
(83)*(38x)=(83)*(132)
x=523
Answer:
x=1713

We may apply a mass balance to determine the amount of water that must be added. The concentration in each of the solutions:
Saline solution: 18%
Pure water: 0%
Final solution: 10%
The volume of each solution is:
Saline solution: 16 oz
Pure water: w
Final solution: 16 + w oz
The moles of a substance are equal to the product of the concentration and volume. Therefore:
16*0.18 + w*0 = (16 + w)*0.1
w = 12.8 ounces
The volume of distilled water that must be added is 12.8 ounces.
Answer:
If each person earns $30, and they split the earnings evenly, then their total amount made would have been $<em><u>120</u></em>. This is because 30(4) = 120. Hope this helps!
