Question

Fie numerele:
a = 40+ 60 : 2-20; b=(17+17×4:17

c=(37×3-37):74.

Calculati 5×a+4×b-3×c+33.

Va rog mult e urgent! ​

Answer 1

a = 40 + 60 : 2 - 20

a = 40 + 30 - 20

a = 70 - 20

a = 50

b = ( 17 + 17 × 4 : 17 )

b = ( 17 + 68 : 17 )

b = ( 17 + 4 )

b = 21

c = ( 37 × 3 - 37 ) : 74

c = ( 111 - 37 ) : 74

c = 74 : 74

c = 1

5 × 50 + 4 × 21 - 3 × 1 + 33 =

250 + 84 - 3 + 33 =

334 - 3 + 33 =

331 + 33 = 364
