Solve for x:
(-3 x)/(8) = (3 x)/8 + 6

Put each term in (3 x)/8 + 6 over the common denominator 8: (3 x)/8 + 6 = (3 x)/8 + 48/8:
(-3 x)/(8) = (3 x)/8 + 48/8

(3 x)/8 + 48/8 = (3 x + 48)/8:
(-3 x)/(8) = (3 x + 48)/8

Multiply both sides by 8:
(-3×8 x)/(8) = (8 (3 x + 48))/8

(8 (-3) x)/8 = 8/8×-3 x = -3 x:
-3 x = (8 (3 x + 48))/8

(8 (3 x + 48))/8 = 8/8×(3 x + 48) = 3 x + 48:
-3 x = 3 x + 48

Subtract 3 x from both sides:
-3 x - 3 x = (3 x - 3 x) + 48

-3 x - 3 x = -6 x:
-6 x = (3 x - 3 x) + 48

3 x - 3 x = 0:
-6 x = 48

Divide both sides of -6 x = 48 by -6:
(-6 x)/(-6) = 48/(-6)

(-6)/(-6) = 1:
x = 48/(-6)

The gcd of 48 and -6 is 6, so 48/(-6) = (6×8)/(6 (-1)) = 6/6×8/(-1) = 8/(-1):
x = 8/(-1)

Multiply numerator and denominator of 8/(-1) by -1:
Answer: |x = -8

If the perfume is 25$ and the percent off is 20

20% x $25 =$5 the discount on perfume.

$25 - $5 =$20 the cost of the perfume after 20% off.

Good luck on your strange quest !

Just try it!. 1/4 + 1/2 = 3/4

You mean "what it feels like when you are being STUPID!!".

Well, you have already answered your own question:

what is 10 to the power of 23 = 10^23

40% of what number is 82

Let the number =N

40%N = 82

0.40N = 82 divide both sides by 0.40

N = 82 / 0.40

N = 205

5+a/2=9 subtract 5 from both sides

a/2 =9 - 5

a/2 =4   cross multiply

a =2 x 4

a =8

Sorry. Disregard Pi/2. It is actually Pi/e.

Here is Pi/e up to 150 digits. Have fun!.

gggggggggggggggggeeeeeeeeeeeeeeeeeeeeet dunked on?

Thanks very much Heureka :))

I'd do it by graphing too but I do not know what asinus has graphed???

I use Desmos Graphing Calculator for my graaphing - it is an only calculator.

I graphed     

\(y=e^x-3e^{-x}+2\)

and this is what I got.

So I can see that this is positive when      x > 0.663    (approximately)

In a flu epidemic 45% of people have sore throat.if a person has a sore throat the probability of not having flu is 0.4 if a person does not have a sore throat the probability of having flu is 0.2 calculate the probability that a person chosen at random has flu

He has a 45% chance of having a sore throat AND if he has a sore throat he has 0.6 chance of having the flu

that is 0.45*0.6 = 0.27

He has a 55% chance of NOT having a sore throat and given that he does not have a sore throat he still has 0.2 chance of having flu

that is 0.55*0.2 = 0.11

so that is    0.27+0.11 = 0.38

A person chosen at random has a 38% chance of having the flu.

WOW that is a lot of sick people - I am not going there!

e^x-3e^(-x)+2>0 {nl} how can i solve this disequation?

The answer is 99 (60+30= 90, 4+5= 9, 90+9= 99)

Rewrite the equation as

2 - 2x = ln(x),

and sketch the two graphs y = 2 - 2x and y = ln(x).

(You shouldn't need a graph plotter to do this).

Solutions to the equation will be the x co-ordinates of their points of intersection. Clearly there is just one, at x = 1.

Hello Melody,

...Euler's formula is true for every polyhedron.

The only polyhedra for which it doesn't work are those that have holes running through them like the one shown in the figure below...

...It involves the Platonic Solids, a well-known class of polyhedra named after the ancient Greek philosopher Plato, in whose writings they first appeared....
