Answer:

$\frac{12}{19} \times \underline{\bold{-1}} = -\frac{12}{19}$

Step-by-step explanation:

$\frac{12}{19} \times ..... = -\frac{12}{19}$

= $\frac{\frac{12}{19}}{-\frac{12}{19}}$

= $\frac{12}{19} \times -\frac{19}{12}$

= $-\frac{228}{228}$

= $\bold{-1}$

So, the appropriate value to complete it is -1

write pythagorean theorem $x^{2}$ + $x^{2}$ = $10^2$

2 $x^2$ = 100

divide 2 both side:

$x^{2}$ = 50

$\sqrt{x^2}$ = $\sqrt{50}$

$x$ = $\sqrt{50}$

$x$ = 7.07106781

round to nearest tenth:

$x$ = 7.1
