No.37 ya.....tolong jawab ok

7x6=42
8x11=88
9x8=72
10x7=70    Di Tambah  = 272:32 = 8.5 
 
Mohon Di Jadikan Yg Terbaik ini Benar gk Salah :v

nilai 7 = 6
= 7 x 6 = 42
nilai 8 = 11
= 8 x 11 = 88
nilai 9 = 8
= 9 x 8 = 72
nilai 10 = 7
= 10 x 7 = 70

nilai = 42 + 88 + 72 + 70 = 272
siswa = 6 + 11 + 8 + 7 = 32

rata = nilai/siswa
= 272/32
= 8, 5
