4. Cimpanzeu= 79 kg
gorila = 250 kg
Cimpanzeu + gorila = 79kg+250kg = 329kg (impreuna)
Gorila -cimpanzeu= 250 kg-79kg= 171kg (cu 171 kg e mai grea gorila)
6. 295= puieti fag
puieti stejar = puieti fag +175
puieti stejar = 295 + 175 = 470
Suma necesara pana la 1000 o notam cu x.
fag +stejar +x = 1000
295 +470 +x=1000
765+x=1000
x= 1000-765
x= 235 puieti
7.
x=(suma)
1807 + 6759 = x
1807 + 6759 = 8566
x= 8566
