18-11=7 to find out how much halve the water weight then subtract 7 from 11 11-7=4 so the emtpy bucket weighs 4 kg
The weight of the empty bucket is 4 kg. This can be determined by setting up equations based on the total weights given in the problem. By solving these equations, we find that the empty bucket weighs 4 kg.

Jawaban:Umar bin KhattabPenjelasan:Umar bin Khattab masuk Islam pada tahun ke-6 kenabian setelah mendengar adiknya (Fatimah binti Khattab) membaca Al-Qur’an (Surah Thaha). Sejak memeluk Islam, Umar dikenal sebagai sahabat yang paling berani membela Nabi Muhammad SAW dan Islam secara terang-terangan. Ia bahkan dijuluki “Al-Faruq”, karena mampu membedakan antara kebenaran dan kebatilan.
