Question

calculeaza4×a÷3+5×c+d÷6,stînd ca:...a=(9000-75÷5-8905)÷4..... b=76×8×(2987-2986)-575 c=3000-(48×7-85÷5)-2669 d=76÷4+45×4+9÷9-164​

Answer 1

a=(9000-75:5-8905):4

a=(9000-15-8905):4

a=80:4

a=20

b=76×8×( 2987-2986)-575

b=608×1-575

b=608-575

b=33

c=3000-(48×7 - 85:5 )-2669

c=3000-(336-17)-2669

c=3000-319-2669

c=12

d=76:4 + 45×4 +9:9-164

d=19+180+1-164

d=200-164

d=36

4×a:3+5×c+d:6=4×20:3 + 5×12 + 36:6 = 80:3+60+6 = 26,2+60+6=92,2

( impartirea 80:3 da cu rest )
