Answer:

The salt is in the water be 3 lb.

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ value}

As given

Twenty pounds of a salt-water solution contains fifteen percent salt.

Let us assume that the salt is in the water be x.

Percentage = 15%

Total value = 20 pounds

Put in the formula

15= \frac{x\times 100}{20}

x = \frac{15\times 20}{100}

x = \frac{300}{100}

x = 3 pounds

or

x = 3 lb

Therefore the salt is in the water be 3 lb.

It doesnt differ lets take 10 = 6 + 4 multiply thru by a negative and flip the sign -10 = -6 - 4 flipping an equals sign about seems redundant, but the process works nonetheless <span>having two separate rules for solving inequalities and equalities seems pointless
