va rog ajutați mă nevoie urgent 3 și 4 dau coroană​ va roggg cat de repede se poate

Answer 1

3. 95-[25:(45:9)+(36:9×3-6)]+786:6=95-[25:5+(4×3-6)]+136=95-[5+(12-6)]+136=95-(5+6)+136=11+136=147

9×(101×1+111:1)-[85-7×(36:9+63:9)]=9×(101+111)-[85-7×(4+7)]=9×212-(85-7×11)=1908-(85-77)=1908-8=1900

4. (36:a+63:9):2=8

36:a+7=8×2

36:a=16-7

a=36:9

a=4

b+149+[(72:8+28:4):4]=396

b+149+[(9+7):4]=396

b+149+(16:4)=396

b+149+4=396

b+149=396-4

b=392-149

b=243

262.625+a=378.070

a=378.070-262.625

a=115.445

448.043-b=152.564

b=448.043-152.564

b=295.479

c-23.325=489.534

c=489.534+23.325

c=512.859
