Question

a×b+[a+(2×c-a:5):2]:7 a=150,b este cum 7mai mare decat jumatatea lui a, iar b impartit la c dau catul4rest6

Answer 1

b=150÷2+7=75+7=82
82÷c=4,6
82=c×4+6
4c=82-6=76
c=76÷4=19
150×82+[150+(2×19-150÷5)÷2]÷7=
12300+[150+8÷2]÷7=
12300+154÷7=
12300+22=12322
sper sa fi facut bine

Answer 2

a=150
b=150÷2+7
b=82
82÷c=4 rest 6
c×4=82-6
c×4=76
c=19
____________
150×82+[150+(2×19-150÷5)÷2]÷7=
12.300+(150+8÷2)÷7=
12.300+156÷6=
12.300+26=12.326
