....... Mg+4dg=160cg
13t-.......q=5000kg​

Answer 1

Explicație pas cu pas:

kg-82 000g=460hg

kg=460hg+82 000g

kg=82 460kg

v:82 460kg-82 000g=460 hg

240hg-g=15g

g=240hg-15g

g=225g

v:240hg-225g=15g

Mg+4dg=160cg

mg=160cg-4dg

mg=156mg

v:156mg+4dg=160cg

q-13t=5 000kg

q=5 000kg+13t

q=5 013g

v:5 013q-13t=5 000kg
