Question

nu știu aflați numărul​

Answer 1

20•e-(1950+550):100=6175

20•e-2500:100=6175

20•e-25=6175

20•e=25+6175

20•e=6200

e=6200:20

e=310

35•f+(800-752:4):2=551

35•f+(800-188):2=551

35•f+612:2=551

35•f+306=551

35•f=551-306

35•f=245

f=245:35

f=7

g:25+(100-1632:51)•2=286

g:25+(100-32)•2=286

g:25+68•2=286

g:25+136=286

g:25=286-136

g:25=150

g=150•25

g=3750

Sper că te-am ajutat!! succes!!
