Question

Calculeaza 3a+5b-12:c,stiind ca=

a=(3:3+9-4):3

b=10-3:(15:5-16-8)

c=(19+6):5-2×(21:7-1)
VA ROG ESTE URGENTTTT

Answer 1

3a+5b-12:c=?
a=(1+9-4):3 =6:3=2
b=10-3:(3-16-8) =10-3:3-8 =10-1-8 =1
c=25:5-2×(3-1) =5-2×2 =5-4 =1
Pana acum e corect de acum in colo e nevoie sa inlicuim literele:
3×2+5×1-12:1 …
=6+5-12=23

Answer 2

a=(3:3+9-4):3=(1+9-4):3=(10-4):3=6:3=2

b=10-3:(15:5-16:8)=10-3:(3-2)=10-3=7

c=(19+6):5-2×(21:7-1)=25:5-2x2=5-4=1
3a+5b-12:c=3x2+5x7-12:1=6+35-12=41-12=29
