Algebra 25 - Linear Equations in the Real World

Linear equations can be used to solve many types of real-world problems. In this episode, the water depth of a pool is shown to be a linear function of time and an equation is developed to model its behavior. Unfortunately, ace Algebra student A.V. Geekman ends up in hot water anyway.

I'm in high school and I struggle with algebra until I found this YouTube channel. I love it. Helps me so much!

[chrisify]

love the way different characters show up! it makes these videos more interesting....GREAT JOB! LOVE THESE VIDEOS!  

[shield]

Great lecture! Keep them coming... PS, it would be great if organisations like Khan Academy could help fund your projects... I really think yours are well explained. You should request funding perhaps?

[FreddieF]

Are you going to make some science or history videos? I would like to see some history of language videos. The subject of linguistic history is very intriguing to me.

[Groundsquirrel]

Nicely done! Always so well presented, very clever and worth waiting for. Love the tutu!

[AngeloGi]

Thank you for this video! Great effort went into it, can't wait for more!

[hello]

Can you help me.Here's the question. Can you site another real life situation using linear equation. Pls I really need this

[droopy_]

Wow. Mighty brilliant mate. Love and regards from India

I'm actually grade 7 and I love math so this where I watch some math that are very easy to me and your videos are amazing, Thank You.

My gosh, thank you! Linear equations are a bit confusing, but you all explained it perfectly.

Also..Geekman's glass defies continuity xD

3:46 Does the initial water level (12 feet) not count as a data point?

[NickBoyd]

I've never seen a below ground swimming pool with a drain plug. Therefore you would need to calculate volume of water over time to pump it out.

[carmenlacunza]

How fast is the water draining out of the pool in feet per hour?

[tamizhtamizh]

In my school times I have imagined myself will there be a teacher doing such stuff... Now it happened ❤

[Ariairzona]

what about the consideration of sunlight that evaporates the water unless the pool was inside but if this was an outside pool it would've decreased more as the day progressed causing the water to be shorter than anticipated.

[HailayKidu]

Oh, late to see this, that is nice and real example

[dr.cherylavila]

I personally like the rather lengthy set up to the problem.  It makes it more "real-world."  In reality problems aren't discovered and solved quickly. The tutu and skateboard are excellent touches. Please start working on the next video while I work my 360s.

Your animations are good. which tools are you using?

[enzo]

Very flexible and interactive. Thanks.
