What is 13.253 as a mixed number<br>sorry to ask again but this is very important ​
Vika [28.1K]

Answer:

13 253/1000

Step-by-step explanation:

To convert 13.253 to a fraction first write it like this:

13.253/1

As we have 3 digits after the decimal point in the numerator, we need to multiply both the numerator and denominator by 10^3= 1000, so that there is no decimal point in the numerator.

13.253 x 1000 / 1 x 1000  = 13253/1000

As the numerator is greater than the denominator, we have an improper fraction, so we can also express 13.253 as a mixed number, thus 13253/1000 is equal to:

13 253/1000

Which of the following are solutions to the equation below? x2 + 6x + 9 =6
svetoff [14.1K]
The correct answer would be 3 +/- \sqrt{6}

In order to solve for this you must first get the equation equal to 0. 

x^2 + 6x + 9 - 6 ----> simplify like terms
x^2 + 6x + 3

Now knowing this we can use the coefficients of each one in descending order of power as a, b and c. 

a = 1 (because it is the coefficient to x^2)
b = 6 (because it is the coefficient to x)
c = 3 (because it is the end number)

Now we can plug these values into the quadratic equation. 

\frac{-b +/- \sqrt{b^{2} - 4ac } }{2a}

\frac{-6 +/- \sqrt{6^{2} - 4(1)(3) } }{2(1)}

3 +/- \sqrt{6}

And those would be your two answers.
