Answer:
P = 
Step-by-step explanation:
Q = 3P + 2 ( subtract 2 from both sides )

Green 6 Can you answer this question for me please 1. What can you see in the picture? 2. What do you think the artist is trying to tell us in the painting? 3. Describe the character of the artist in three words.
When the concentration of a solution is expressed in weight percentages, that is just equal to the mass of solute over the mass of the total solution. For a solution weighing 210 grams, 5% of it is salt. That is equal to
210*0.05= 10.5 g salt
The rest of the amount, determined by difference, is the amount of solvent which is water.
water = 210-10.5 = 199.5 g salt
To solve for the new concentration, you add up 15 g to the already existing 10.5 g of salt in the solution. The water, on the other hand, remains constant.
Concentration = (15+10.5)/(210+15) = 0.1133 or 11.33%
