6 0

Answer:

11

Step-by-step explanation:

Making the appropriate substitutions, we get

3/7 r + 5/8 s  =>  3/7 (14) + 5/8 (8).

Notice how this can reduced:

                             3(14)            5(8)

                           ----------- +     ---------   =   6 + 5 = 11

                                  7                8

dalvyx [7]

Answer:

\boxed{\sf \ \ \ m = -\dfrac{tn}{t-s} \ \ \ }

Step-by-step explanation:

Hello,

let s assume that m+n is different from 0

we have this equation and we need to find m as a function of t, s, and n

t=\dfrac{ms}{m+n}

<=>

(m+n)*t=ms\\\\ tm+tn=sm\\ (t-s)m = -tn\\ m = -\dfrac{tn}{t-s}

for t-s different from 0, so t different from s

hope this helps
