Question

Решите уравнения:
1) -2,6z=5,46
2) n:(-6,8)=3,4
3)-4/9:y=3целых 5/9

Answer 1

$1) - 2.6z = 5.46 \ z = - 2.1 \ 2) frac{n}{ - 6.8} = 3.4 \ n = 3.4 times ( - 6.8) \ n = - 23.12 \ 3) - frac { 4}{9} div y = 3 frac{5}{9} \ frac{32}{9} y = - frac{4}{9} \ y = - frac{4}{9} times frac{9}{32} \ y = - frac{1}{8}$

Answer 2

1. -2,6z=5,46
z=5,46/(-2,6)
z=-2,1.

2.
$frac{n}{ - 6.8} = 3.4 \ n = 3.4 times ( - 6.8) \ n = - 23.12$
3. -4y/9 = 32/9
-4y=32
y=-8.
