b . strata 60 i strata 30 to _______ - 60 + ( -30 ) = ___
c . strata 21 i strata 19 to ____ ___ + ____ = ____
d . strata 70 i zysk 80 to ______ - 70 + 80 = _____
e . zysk 10 i strata 12 to _____ 10 + ( - 12 ) =
f . strata 17 i zysk 15 to _____ ____ + ____ = ____
g . zysk 65 i strata 110 to _____ ______ + ___ = ___
h . strata 3,5 i zysk 7,5 to _______ ____ + ____ = ____

Answer 1

A . strata 6 i strata 7 to (-13) -6 + ( -7 ) = -13
b . strata 60 i strata 30 to (-90) - 60 + ( -30 ) = -90
c . strata 21 i strata 19 to (-40) -21+ (-19) = -40
d . strata 70 i zysk 80 to 10 - 70 + 80 = 10
e . zysk 10 i strata 12 to -2 10 + ( - 12 ) = -2
f . strata 17 i zysk 15 to -2 -17 + 15 = -2
g . zysk 65 i strata 110 to -45 65 + (-110) = -45
h . strata 3,5 i zysk 7,5 to 4 -3.5 + 7,5 = 4

Answer 2

A) -6+(-7)=-6-7= -13
b) -60+(-30)=-60-30= -90
c) -21+(-19)=-21-19= -40
d) -70+80= 10
e) 10+(-12)= 10-12= -2
f) -17+15= -2
g) 65+(-110)=65-110= -35
h) -3,5+7,5= 4


Mam nadzieję że pomogłam.. ;)

Answer 3

A. strata 13 -6+(-7)=-13
b. strata 90 - 60 + ( -30 ) =-90
c. strata 21 i strata 19 to strata 40 -21 + (-19) = -40
d. strata 70 i zysk 80 to zysk 10 - 70 + 80 = 10
e. zysk 10 i strata 12 to strata 2 10 + ( - 12 ) = -2
f . strata 17 i zysk 15 to strata 2 -17 + 15 = -2
g . zysk 65 i strata 110 to strata 45 65 + (-110) = -45
h . strata 3,5 i zysk 7,5 to zysk 4 -3.5 + 7.5 = 4
