What kind of triangle is it? Right, Equilateral, Isoceles.......etc.

4/3 x 328 =~437 votes

(2x +1) / 3, simplify: Put both terms under the same denominator of 3:

(2x)/3 + 1/3. That is all you can do with it.

Yay Thanks! It's correct! You rock Melody!

Hi Sophie :)

Free the x in 2x+1 over 3

Hey I have to simplify this by rewriting the division

Perhaps this is what you mean?

\(\frac{2x+1}{3}=\frac{2x}{3}+\frac{1}{3}=\frac{2}{3}x+\frac{1}{3}\)

or

\(\frac{2x+1}{3}=(2x+1)\div3=2x\div3+1\div3\)

There can be infinite answers because the quantity of x can be changed to any number. So, the equation is incorrect.

Actually I'm not solving for x i have to free it from this fraction in conclusion I am simplifying the problem i don't have to solve the whole equation just simplify but thank you for that awesome answer!

By "free the x", I assume you mean "solve for x":

Solve for x:
(2 x + 1)/3 = 0

Multiply both sides of (2 x + 1)/3 = 0 by 3:
1 (2 x + 1) = 3×0

(3 (2 x + 1))/3 = 3/3×(2 x + 1) = 2 x + 1:
2 x + 1 = 3×0

0×3 = 0:
2 x + 1 = 0

Subtract 1 from both sides:
2 x + (1 - 1) = -1

1 - 1 = 0:
2 x = -1

Divide both sides of 2 x = -1 by 2:
(2 x)/2 = (-1)/2

2/2 = 1:
Answer: |x = (-1)/2 =- 1/2

You should write your equation as 54+(x-2)=2x and your answer will be correct x=52

x=-56

"Suppose a standard 12hour clock now shows a time of 10:45 what time will the clock show 100hours from now"

Every 12 hours it will be 10:45 again, so narrow it down like this.

12, 24, 36, 48, 60, 72, 84, and 96 hours from now, it will be 10:45.

So let's say 96 hours pass - it's 10:45.. now you just have 4 more hours left to hit 100.

4 hours after 10:45 means that it will be 14:45, or 2:45.

Therefore, after 100 hours, the clock will show 2:45.

Let us say it is: 10:45 AM.

1 day = 24 hours

100 / 24 =4 1/6 days, or 4 days and 4 hours from 10:45 AM today, which will be Friday, Dec, 16, 2016 at 2:45 PM.

With most triangles I'm pretty sure you add up the side lengths that you already know and then subtract that number from 180 to get the 3rd side length

CORRECTION: y^-3 / x^-2 =x^2 / y^3

if 90=42x+6, what is x?

42x+6=90   |-6

    42x=84   | :42

        x=2

y^-3 / x^-3 = x^3 / y^3

f(x)=-2x^2+8x+25

\(f(x)=2x^2+8x+25\)

             a         b         c

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)

\(x = {-8 \pm \sqrt{8^2-4*2*25} \over 2*2}\)

\(x= -2\pm\sqrt{-136}\)

\(x_1=-2+11.662\ i\)

\(x_2=-2-11.662\ i\)
