so Meg's friend is a faster reader, if Meg takes 3/5 of an hour I guess, to read one book, her friend takes 2/3 of that.

how much is 2/3 of 3/5?  well, is just their product.


\bf \cfrac{3}{5}\cdot \cfrac{2}{3}\implies \cfrac{3}{3}\cdot \cfrac{2}{5}\implies 1\cdot \cfrac{2}{5}\implies \cfrac{2}{5}\impliedby \textit{for one book only} \\\\\\ \stackrel{first~book}{\cfrac{2}{5}}+\stackrel{second~book}{\cfrac{2}{5}}+\stackrel{third~book}{\cfrac{2}{5}}\implies \cfrac{6}{5}\implies 1\frac{1}{5}\impliedby \textit{for three books}

Essential: Solve the proportions<br> step by step ​
vazorg [7]

Answer:

The value of r=\frac{-106}{47}

The value of x=\frac{83}{32}

Step-by-step explanation:

Given that,

A) \frac{2r-2}{7r+10} = \frac{9}{8}

Now,

\frac{2r-2}{7r+10} = \frac{9}{8}

8(2r-2)=9(7r+10)

16r-16=63r+90

-16-90=63r-16r

-(16+90)=47r

-106=47r

r=\frac{-106}{47}

B) \frac{x+4}{9} = \frac{3(x-2)-1}{5}

Now,

\frac{x+4}{9} = \frac{3(x-2)-1}{5}

5(x+5)=9[3(x-2)-1]

5x+25=9[3x-6-1]

5x+25=9[3x-7]

5x+25=27x-63

25+63=27x+5x

83=32x

x=\frac{83}{32}
