Пошаговое объяснение:
1) 5+(10+m) =5+10+m=15+m
2) 96-(n+32) =96-n-32=64-n
3) 19+(-10-k) =19-10-k=9-k
4) (30+x) -x=30+x-x=30
5) c+(15+c) =c+15+c=2c+15
6) (2+y) -(y-10) =2+y-y+10=12
7) -(15-a) =-15+a
8) -20+(k-10) =-20+k-10=k-30
9) (m+x) -(-10-x) =m+x+10+x=m+2x+10
10) -(y+15) +(5y+6) =-y-15+5y+6=4y-9
2.) 73.32:((15.41-14.76) *1.6) +55.186:6.73=73.32:(0.65*1.6) +8.2=73.32:1.04+8.2=70.5+8.2=78.7
