Mixture problems 3

Missed the previous lesson?

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

How do you do a mixture problem that contains percentages?

[LuizitoPollo]

What process can you use to help you write a system of linear equations when dealing with mixture problems?

[MODSUM]

yes he is. he has a banner, hence the little decorated link in the top left corner. also. people have the choice to put ads in the front or not. it really depends on who partners the channel. you can choose not to put ads.

[fathobo]

He is NOT a youtube partner. There are NO ads in front of his videos.

Can someone please solve this using the table approach discussed in the video: A substance is 99% water. Some water evaporates, leaving a substance that is 98% water. How much of the water evaporated?


Answer is 50.5% evaporated. Someone, please provide a generalized equation.

I'm not sure how many times he repeated every word.
