Question

Completati spatiile punctate cu raspunsul corect:

a. Solutia ecuatiei x+1/4=1,5 este numarul rational....

b. Daca x supra 6=1,1(6), atunci x este egal cu...

c. Rezolvand ecuatia 2x-3 pe 2=2,5-2x obtinem solutia naturala.....

Answer 1

x=1,5-0,25=1,25
b)x/6=1,1(6)
x/6=105/90
x=6·105/90=7
c)2x-3/2,5-2x=2
2x-3=2*2,5-2x
2x-3=5-2x
4x=8
x=2
