I instinctively used method 2, probably because it has been too long since I had to use ,method 1 in daily life. But it is nice to be reminded of method one, because that is more broadly applicable.
My way of solution ▶ The height of the glasses: x The height of each glass when placed inside the other: y ⇒ x+4y= 29 cm x+y= 17 cm ⇒ x+4y= 29 -x-y= -17 ⇒ 3y= 12 y= 4 cm x+4y= 29 y= 4 ⇒ x= 13 cm ✅
You can do it in about 10 seconds. 3 more glasses give you 12 more cm. Therefore one glass inside another one adds 4cm. Hence the height of the glass is 13cm.
It has something relaxing to watch you do the math. 😁 I think about the problem for a minute and then I watch your video.
Aaaaw, thank you so much! It’s great, that you enjoy it!

Great, that you could solve it! Yes, equations are usually not a part of our daily lives. 😄
This was fun, thank you! I used equations to solve it, but I really like your second method.
Nice, that you tried it yourself and that it worked! The beautiful thing about math is, that there are so many ways to solve a problem.
I solved this before looking at your solution and I did it graphically. 🙂
Awesome that you successfully tried yourself!
My way of solution ▶
The height of the glasses: x
The height of each glass when placed inside the other: y
⇒
x+4y= 29 cm
x+y= 17 cm
⇒
x+4y= 29
-x-y= -17
⇒
3y= 12
y= 4 cm
x+4y= 29
y= 4
⇒
x= 13 cm ✅
Dankeschön ❤❤
i prefer both method and your funny explanation
except you cant prefer both methods :3
+3 glasses = +12 cm, so each + = 4cm
29 -12 =13cm
5 seconds in my head
And 30 it only take 30 second
13. I solved this for 30 sec
Awesome! Which way did you take?
