9x - 7i > 9x - 21u
-7i > -21u
-i > -3u
i < 3u

Not sure how to proceed from here.

I have become really bad at math. What happened to me?

 

Spoiler: Answer

i < 3u

Also, very clever with the answer as well ' i <3 u' hehe...

 

You both got it. Conglaturation.

 

I remember maths. Yeah... good times.

 

Your post disappeared, Ventus108, but the answer is 509.901951359.

 

2 years since I've had to do maths of any kind, I have come to realise that I don't remember jack.

 

Don't worry, algebra is still simple.

 

Math was the only class I paid attention in, but I don't remember any of this.

 

History and Biology for me, I liked maths, not good at it though.

 

so glad none of my high school teachers even cared if we learned/remembered what we were being taught
all of this is seriously making my brain hurt

i don't remember how to do anything.

 

This thread has rekindled my inner math spark. Consequently, I happened to indulge myself in solving an algebraic division problem, and I'd like to request some help:

Spoiler

Here's what I have so far:

• b>a

• n/a>n/b

• a/a + n/a>b/b + n/b

• (a+n)/a>(b+n)/b

• (a+n)/(b+n)>a/b

Similarly, if you have a>b, then (a+n)/(b+n)<a/b.

From what I see, given any n>>>>>>>>>a,b, these two become negligible, more so if n is given even higher values to.

Thoughts?

 

WHEN WiLL WE EVER USE THIS IN LIFE?

 

All of the time. Algebra is applied in a ton of basic logic, you just don't think about it.

If you don't work in manual labor, this stuff if good to know. Especially geometry and trigonometry.

 

It's called problem solving
You do it most everyday.
Almost ever decision you make can be broken down into numbers and variables.

 

Calculus is used in pharmacy when determining drug detoxification in the body (my dad has to use it at work sometimes).

I have used Trig and geometry in the last year to measure the areas of rooms and the garden for how much carpet and turf we needed.

it's not really useless, people just don't often think of the applications as they're not immediately obvious.
