Simplify 6x/10x2\6/10x3-60x2<br> A.x-6<br> B.x-4<br> C.4<br> D.x-1

Anna71 [15]

Answer:

A. x-6

Step-by-step explanation:

Maybe you want to simplify ...

((6x)/(10x^2))/(6/(10x^3 -60x^2))

Invert and multiply. Cancel common factors from numerator and denominator.

$\dfrac{\left(\dfrac{6x}{10x^2}\right)}{\left(\dfrac{6}{10x^3-60x^2}\right)}=\dfrac{6x}{10x^2}\cdot\dfrac{10x^3-60x^2}{6}=\dfrac{6\cdot10x^2}{6\cdot10x^2}(x-6)\\\\=\boxed{x-6}$

If you reflect any shape across the x-axis and then rotate it 90° clockwise about the origin, do you get the same result as if y

Setler79 [48]

Answer:

Yes, reflecting a shape across the x-axis and then rotating it 90° clockwise about the origin gives the same results as reflecting it across the y-axis followed by rotating it 90° counterclockwise about the origin. This means these two sequences of transformations are equivalent.

The sum of x and 3/5 is 5/7.

crimeas [40]

We first write the word in math as x+3/5 = 5/7. Now we cross multiply our fractions and rewrite them with the LCD of 5 and 7. Our equation now looks like x + 21/35 = 25/35. We simplify our equation by subtracting 21/35 from both sides to get x = 4/35. 4/35 is already in lowest terms so it is our answer.

Write a short paragraph discussing the reasons why someone should make a will.

LuckyWell [14K]

When someone dies everyone wonders what will happen to all of their possessions. If the person had a will then everyone will know what they have to keep. If the person did not have a will then no one will know what to keep and what not to keep. That can cause problems among family and friends. To keep the peace and sentimental value in balance a will is very important to make.

lesantik [10]

Answer:

The overall reliability is 99.7402 %

Step-by-step explanation:

The overall reliability of the product is calculated as the product of the working probability of the components.

For components A,B,C and F we have :

$P(failure)=\frac{1}{10000}$
