34

Step-by-step explanation:

Let x be the amount of water in the bottle

6.8 ounces is 20 % of the amount of water in the bottle

6.8 = 20% * x

6.7 = .20x

Divide each side by .2

6.8 /.2 = x

34 =x

There are 34 ounces in a full bottle

34 ounces

Step-by-step explanation:

so you know that 20% is 6.8 ounces so in order to find 100% you will multiply 6.8 x 5 you will times it by 5 because you divide 100 by 20 so,

6.8 ounces x 5 = 34 ounces

100% = 34 ounces

hope this makes sense if not message and i will explain on what you are struggling with

b.an increase in a causes b to decrease

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
