b)x*838=1257,48
c)x:7,4=5,6
d)23,576:x=29,47

Answer 1

1) rezolvati ecuatiile:
a) 235+ x=347,59
x=347,59-235=112,59
b)x +25,17=32,15
x=32,15-25,176,98
c)x-176=121,36
x=121,36+176=267,36
d)101,57-x=14,07
x=101,57-14,07=87,5
2) rezolvati in multimea numerelor rationale ecuatiile:
a)14,7*x=2,94
x=2,94/14,7=0,2
b)x*838=1257,48
x=1257,48/838≈1,50057279
c)x:7,4=5,6
x=5,6/7,4=0,(756)
d)23,576:x=29,47
x=29,47/23,576=1,25
