12.?
Penjelasan dengan langkah-langkah:
7. 8+10+12 = 30 : 3 = 10
8. 21+13+14+12 = 60 : 4 = 15
9. 5,8 liter x 8 = 46,4 liter
10. 48 x 5 = 240
11. average mass of james,john,robby = 42kg
total mass of them 42 x 3 = 126kg
total mass of james and john = 78kg
mass of robby is 126kg - 78kg = 48kg
12. total average amount Rp.56.000
56.000 : 2 (ucok dan arti) = 28.000
ucok spent Rp.14000 more than arti.
so total ucok spent's = 28.000 + 14.000 = 42.000
