There are 5,040 different ways in which she can order the books.

<h3>In how many ways can she put the books on the shelf?</h3>

We know that Donna has 9 books, but 2 of these books already have fixed positions (the first one and the last one).

So we only need to order the remaining 7 books in 7 positions.

  • On the first position, we have 7 options (7 books to put there).
  • On the second position, we have 6 options (because one book is already in the first position).
  • On the third position, we have 5 options.

And so on for the remaining positions.

The total number of different combinations in which she can order the books is given by the product between the numbers of options above, so we will get:

C = 7*6*5*4*3*2*1 = 5,040

Can anyone find the answers this for these question but make them fractions
k0ka [10]

We are given fractions \frac{77672}{5548} and \frac{288184}{34}.

In order to write them in simplest fractions, we need to find a common number that can divide both top and bottom.

Let us work on simplifying first fraction first.

\frac{77672}{5548}

We have 77672 on the top and 5548 in the bottom.

The greatest number 5548 can divide both 77672 and 5548 both.

Dividing 77672 by 5548, we get 14 and dividing 5548 by 5548 we get 1.

Putting quotent 14 on the top and 1 in the bottom, we get

\frac{14}{1}  . This is the answer for first part.

Let us work on simplifying second fraction \frac{288184}{34}.

Top number 288184 and bottom number 34, both can be divided by 34.

On dividing 288184 by 34, we get 8476 and dividing 34 by 34, we get 1.

Putting quotent 8476 on the top and 1 in the bottom, we get

\frac{8476}{1}.   This is the answer for second part.

Which equations have the same value of x as Three-fifths (30 x minus 15) = 72? Select three options.
Anon25 [30]

An equation is formed of two equal expressions. The correct options are C, D, and E.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The value of x in the given equation is,

\dfrac35 (30x-15) = 72\\\\(6x - 3) = 72\\\\6x -3 = \dfrac{72}3\\\\6x = 24 + 3\\\\x = 4.5

Substitute the value of x in other option to check if the equations are equal are not. Therefore, the options can be written  as,

A.) 18x - 15 = 72

18(4.5) - 15 = 66

Thus, this will not return the same value.

B.) 50x - 25 = 72

50(4.5) - 25 = 200

Thus, this will not return the same value.

C.) 18x - 9 = 72

18(4.5) - 9 = 72

Thus, this will return the same value.

D.) 3(6x - 3) = 72

3[6(4.5) - 3] = 72

Thus, this will return the same value.

E.) x = 4.5

Thus, this will return the same value.

Hence, the correct options are C, D, and E.
