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
