20/10 as a mixed number

2 answers:

First, decide how many times 10 can go into 20. 10 can "fit in" to 20 exactly 2 times. Since there is nothing left over, the "mixed number" is simply 2.
Another way to do this is to just divide the top by bottom, since it will divide evenly.
20/10 = 2.
Answer: 2
Hope that helps!!

20/10 is not possible being a mixed number, simply because 10 can go into 20 evenly.

2 is the answer.

What is the factored form of x^3-1

polet [3.4K]

Answer:

the factors of x^3-1 are $x^3 -1 = (x-1) (x^2 +x+1)\\$

Step-by-step explanation:

We need to find factors of x^3 -1

$x^3-1 \\(x)^3 -(1)^3\\We \,\, know\,\, a^3 -b^3 = (a-b) (a^2 +ab + y^2) \\So, \,\, using\,\, the \,\, formula\,\,\\Here\,\, a= x \,\,and\,\, b= 1\\(x)^3 -(1)^3 = (x-1) (x^2 +x+1)\\$

So, the factors of x^3-1 are $x^3 -1 = (x-1) (x^2 +x+1)\\$

PLEASE HELP. TAKE AT HOME TEST. if u = LN5 and v = LN2, write LN8/15 in terms of u and v. (8/15 is 8 over 25)

astra-53 [7]

Answer:

$\ln( \frac{8}{25} ) = 3v - 2u$

Step-by-step explanation:

We have that

$u= \ln(5)$

and

$v = \ln2$

This implies that;

$5 = {e}^{u}$

and

$2 = {e}^{v}$

Now find and expresion for

$\ln( \frac{8}{25} )$

Which is

$\ln( \frac{8}{25} ) = ln(8) - ln(25)$

$\ln( \frac{8}{25} ) = ln( {2}^{3} ) - ln( {5}^{2} )$

$\ln( \frac{8}{25} ) = 3 ln( {2} ) - 2ln(5)$

$\ln( \frac{8}{25} ) = 3v - 2u$

Enter the value if x+27

Sonja [21]

Answer:

Shown Below

Step-by-step explanation:

Alright so first off we are going to use the little 67 on that corner. We know that it's a supplementary angle, and supplementary angles add up to 180.

180 - 67 = 113.

Inside angles of a triangle all add up to 180. Using that we can create the equation:

(x + 27) + x + 113 = 180

simplify.

2x + 140 = 180

subtract 140 on both sides.

2x = 40

divide both sides by 2

x = 20

substitute x into the asked equation.

(20 + 27) = 47

47 is your answer.
