almond37 [142]

Answer:

Step-by-step explanation:

1/8 = 1/9 + x ...multiply by LCD of 72

9 = 8 + 72x

9 - 8 = 72x

1 = 72x

1/72 = x

1/8 = 1/10 + x....multiply by 40

5 = 4 + 40x

5 - 4 = 40x

1 = 40x

1/40 = x

1/8 = 1/11 + x....multiply by 88

11 = 8 + 88x

11 - 8 = 88x

3 = 88x

3/88 = x

can all unit fractions be made in more then 1 way like this ?

not to sure because that last one....because it has been that a unit fraction is the outcome of adding together 2 unit fractions...but that last one...3/88 is not a unit fraction

Thea has a key on her calculator marked $\textcolor{blue}{\bf\circledast}$. If an integer is displayed, pressing the $\textcolor
mel-nik [20]

Answer:

$9$

Step-by-step explanation:

Given: Thea enters a positive integer into her calculator, then squares it, then presses the $\textcolor{blue}{\bf\circledast}$ key, then squares the result, then presses the $\textcolor{blue}{\bf\circledast}$ key again such that the calculator displays final number as $243$.

To find: number that Thea originally entered

Solution:

The final number is $243$.

As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,

the number before $243$ must be $324$.

As previously the number was squared, so the number before $324$ must be $18$.

As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,

the number before $18$ must be $81$

As previously the number was squared, so the number before $81$ must be $9$.
