Question

Fie a=127-3×12,b=134+2×17+432:4:3sic=17×12-576:6:4-12. Calcolati:11×a-3×(b-c). b)3×a+2×b--c si c)4×(a+b)-5×c

Answer 1

A=127-36 <=> A=91
B=134+34+108:3 <=> B= 134+34+36 <=> B= 168+36 <=> B= 204
(Ba ce naiba scrie si tu despratit :D sic am crezut cai sin (sinus)
C=17x12-576:6:4-12 <=> C= 204-96:4-12 <=> C= 204-24-12 <=> C= 180-12 <=> C= 168.
a) 11x91-3x36 = 1001-108=893
b) 3x91+2x204-168 = 273 + 408 - 168 = 681-168=513
c) 4x(91+204)-5x168=4x295-5x168=1180-840=340
