Ayo bantu dong jawabnya
peri = 45. 45 ÷ 3 = 15 satu peri
bintang = 21. 21 ÷ 3 = 7 satu bintang
sapu = 12. 12 ÷ 3 = 4 satu bintang
pertanyaannya
sapu + (peri × bintang)
4 + (15 × 7)
4 + 105
109
• 3x = 45
x = 45 : 3
x = 15
• 3x = 21
x = 21 : 3
x = 7
• 3x = 12
x = 12 : 3
x = 4
• 4 + 15 × 7
=> 4 + 105
=> 109
