D (9-6) (-2) + (13 + 3):(-4)=

Answer 1

Respuesta:

a) 19+3 x (5-8)= 19+3 x -3=19-9=10

b) 12-5 x 18 -9 = 12-90-9= -87

c) 12-(13+7)/-5=12-20/-5= 122+4= 16

d) 10-20/7-3= 29/7

e) -2 x -2 + 9 x 2 = 10

f) 3 x -2 + 16/4= -6+4= -2

Answer 2

Respuesta:

Espero haberte ayudado.

Explicación paso a paso:

a) 19 - (-3) . [5-(+8)]

19 +3 . (-3)

22 x (-3) = - 66

b) 12 + (-5) . 18 + (-9)]=

12 - 90 - 9 = -87

c) 12- [13 - (-7)] : (-5)

12 - (13 + 7) : (-5)

12 - 20 : (-5)

12 + 4 = 16

d) 10 - (+20) : 7 + (-3)] =

10 - 20/7 -3 =

7 - 20/7 = 29/7

e) (-2) .(5 - 7) - (-3) . (8 - 6)

(-2) . (-2) + 3 . 2

2 x 2 + 3 x 2

2 (2 + 3)

2 x 5 = 10
