31/10s = 31/5
5×31s=31×10
155s = 310
s=310/155= 2


20/9=-4/5m
5×20=-4×9m
100=-36m
m=100/-36 = 72 28/36 = 72 7/9


-14/5=-7/2n
-14×2=5×-7n
-28=-35n
n =-28/-35

Nadusha1986 [10]

Answer:

 ≈ <em>3.4</em><em> </em>

Step-by-step explanation:

Coordinates of the point that divide segment with endpoints A( x_{1} , y_{1} ) and B( x_{2} , y_{2} ) in a ratio a : b are

\frac{bx_{1} +ax_{2} }{a+b} , \frac{by_{1} +ay_{2} }{a+b} )

A(- 4, - 7)

B(8, - 4)

Ratio 8 : 5

x-coordinate is \frac{5(-4)+8(8)}{8+5} = \frac{44}{13} ≈ <em>3.4</em>
