Answer 1

Respuesta:

A) (+72) + (. )= 123

(. )= 123-72

(. )=51

(+72)+(51)= 123

B) (-16) + ( )= 9

(. ) = 9 - (-16)

(. ) = 25

(-16)+(25) = 9

C) (. ) + (-216) = -315

(. )= -315 - (-216)

(. )= -99

(-99)+(-216)= -315

D) ( b)+(+ 16.4) = 25.9

(b)=25.9-(+16.4)

(b)= 9.5

(9.5)+(16.4)= 25.9

E) ( ) + (-2.9) = 3.5

(. )=3.5-(-2.9)

(. )= 6.4

(6.4)+(-2.9)= 3.5

f) (-16.5) + ( )= -3.7

(. )= -3.7 - (-16.5)

(. )= 12.8

(-16.5)+(12.8)= -3.7
