Answer 1

Respuesta:

Explicación paso a paso:

a) 16 ÷ ( - 2 ) – ( - 4 ) + 5 · ( - 1 ) =  -9

-8 + 4 + (-5) =

-4 -5= -9

b) 4 – ( - 5 ) – 15 ÷ ( - 5 ) + 4 · ( - 2 ) =  4

4 + 5 - (-3) + (-8) =

9 + 3 - 8 =

12 - 8 = 4

c) 8 ÷ ( - 4 ) – ( – 3 ) + 3 · 2 =  7

-2 + 3 + 6 =

1 + 6 = 7

d) 8 – 6 ÷ ( - 3 ) + 4 · ( - 2 ) + 5 · ( - 10 ) =  -48

8 - (-2) + (-8) + (-50)=

8 + 2 - 8 - 50 =

10 - 8 - 50 =

2 - 50 = -48

e) 3 – 4 ÷ (- 4) + 4 · ( - 4 ) – 1 = -13

3 - (-1) + (-16) -1 =

3 + 1 -16 -1 =

(3+1) - (16+1) =

4 - 17 = -13
