If you mean:  p - 4/p  =  16/(5p) - 1/5

Multiply each term by the lowest common denominator, 5p:

--->   5p² -20  =  16 - p

--->   5p² + p - 36  =  0

Using the quadratic formula, with a = 5, b = 1, and c = -36:

--->  p  =  [-1 ± √( (-1)² - 4(5)(-36) ] / ( 2 · 5 )

If you mean:  p - 4/p  =  (16/5)p - 1/5

Multiply each term by 5p:

--->   5p² - 20  =  16p² - p

--->   -11p² + p - 20  =  0

if you use the quadratic formula, you will not get real answers.

If the problem is (2/3)y  =  1/4, multiply both sides by 3/2   -->   y  =  3/8

If the problem is 2/(3y)  =  1/4, then cross-multiply:  (3y)(1)  =  (2)(4)      --->      3y = 8   --->   y = 8/3

a/x - 1/c  =  b/d

Since you are solving for b, get the b-term alone. To get rid of the "divided by d", multiply both sides by b:

(a/x - 1/c)d  =  b

Since it is only an expression, not an equation, you can't determine what it equals.

Since they all hav the same charge, divide them into 6 equal parts:  -48 ÷ 6  =  -8

5/5  =  1

1 ÷ 1/2  =  1 x 2/1  =  2/1  =  2

When dividing by a fraction, multiply by its multiplicative inverse; the multiplicative inverse of 1/2 is 2/1.

The volume of a prism is the area of the base times the height; the area of the base is 60 and the height is 13; so the volume is 60 x 13 =  ... (meters cubed).

Since the prism is right, the length of a lateral edge is the height of the prism.

Well Alan and Melody explain it to you so now all you have to do is change your mind. That is easer than changing all the math rules.

I figure out that Santa Clause is not real when I was 6. Even though I think he was real that not make it true. My little sister figured it out but she keep changing her mind because she not want to hurt his feelings if he is real. Hahaha She probably make up her mind before she is 8.

If you want to use Latex to write things on here then you should learn how to do that too. Mathgod know how to use it and he is 12. He know how to do math better than you too.

{Melody I agree with you 8 - 3^2 = 8 - 9 = -1 ${ but my question is how much is } -2^2 ${ to me should be +4}$$

Take the battery out. hahaha

Hi Z

Anon make mistakes.

x-8y=-56

Rewrite it like this in slope intercept form

-8y = -56 - x

8y = 56 + x

Y= 7 + x/8

Y = x/8 + 7

y = 0.125x + 7

The slope is 0.125

The slope intercept is +7 This means the line cross the y at +7

I think this is right but one of the mods should check.

cross multiply

I'd change it to 8y=x+56. Then (since it's terrible to have a number in front of y) I'd divide the whole equation by 8. Now the equation is y=(1/8)x+7. The slope is always in front of x, which is (1/8). The y-intercept is the lonely number, which is 8. I hope this helps! :)

 Hello 

Hover the cursor over the button, or just press the 2nd button (top left).

p = 1.8 or -2

Get the LCM of a and b which is ab then divide accordingly. You should get ((b-2a)/ab) / ((2b-a)/ab) then after cancelling ab on both sides, you remain with (b-2a) / (2b-a)

Answer is 1. Anything to power 0 is 1

p-4/p + 16/5p - 1/5 =?

Rosala, TR probably play Farmville all the time in secret. That is how he feed all his soldiers. hahaha

Thanks!

You know jwveverka you probably not have to learn maths all over. The maths on Earth is the same as the maths in outer space.

Maybe maths is different in Brazil though

I agree with you 8 - 3^2 = 8 - 9 = -1
but my question is how much is -2^2

to me should be +4$$
