Answer:
n is less than or equal to 48.
Step-by-step explanation:
He weighs 100 lbs.
So: 340 - 100 = 240 - remaining weight for packages.
240/5 = 48.
He can carry 48 packages at most with him.

Answer:
x = - 5
Step-by-step explanation:
Using the rule of exponents
• 
⇔ 
Given
= 32
= 32
= 
Since the bases are equal, both 5, equate the exponents
Hence x = - 5
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%
