Okay, based on your logic, what would:
Six times a number is four less than 8 times a number

Okay now I'm doubting myself. Let me step back and reassess this.
OpenStudy (anonymous):
Okay I'm almost positive I'm right. Replace the numbers with what they mean.
OpenStudy (anonymous):
6x >= 8x - 4
six x is greater than or equal to eight x minus four.

Hell, let's use your equation and see if it's true.
OpenStudy (anonymous):
6x >= 8x - 4
-2x >= -4
x >= 4
6(4) >= 8(4) - 4
24 >= 32 - 4
24 >= 28
FALSE!
OpenStudy (anonymous):
Boomshakalaka. And sorry that you're wrong. o.o
OpenStudy (anonymous):
very confused.
OpenStudy (anonymous):
You see how I solved for x using your equation right?

Wait, did it wrong. derp
OpenStudy (anonymous):
x >= 8
OpenStudy (anonymous):
6(8) >= 8(8) - 4
48 >= 64 - 4
48 >= 60
Still wrong.
OpenStudy (anonymous):
According to @ganeshie8 my answer is right..
OpenStudy (anonymous):

I(x) am atleast 5 inch tall means :
x >= 5
OpenStudy (anonymous):
It said "at least" , we were stuck and he confirmed that my answer was right.
OpenStudy (anonymous):
But how come when you solve for x it comes out false?
ganeshie8 (ganeshie8):
`a quantity` is atleast `something` means :
`a quantity` >= `something`
ganeshie8 (ganeshie8):
lets see

6x >= 8x - 4
-2x >= -4
x <= 2
so the solutions are (-inft, 2]
OpenStudy (anonymous):
Oh my god I MULTIPLIED BY 2 *shoots self*
ganeshie8 (ganeshie8):
haha happens :)
OpenStudy (anonymous):
lol I guess. Thanks for clearing that up. :D
ganeshie8 (ganeshie8):
