Question

cine ma ajuta sa fac ex 10,11 si 12 dau coroana. ps : am nevoie urgent va rog

Answer 1

10. (a+b+c):c➡️(5+4+1):2=10:2=5

a×b+c×d➡️5×4+2×1=22

(a+c)×(b+d)➡️(5+3)×(4+1)=40

a×b-c×d➡️5×4-2×1=18

(a+b):(c+d)➡️5+4:2+1=8(5+2+1)

(a+c+d):b➡️(5+2+1):4=2

11.(a+b+c):2➡️(6+5+3):2=14:2=7

(a×b):(c×d)➡️(6×5):(3×2)=5(30:6)

(a+d):(b+c)➡️(6+2):(5+3)=1(8:8)

(a-c):(b-d)➡️(6-3):(5-2)=1(3:3)

12.a=(81-57):8+10-72:9=5

b=7×6×0+10+4×10+0:9=50

50×5=250

Special că te-am ajutat!♥️
