+ Từ láy: mênh mông, rập rờn => gợi tả không gian rộng lớn, bao la của cánh đồng lúa+ Đảo ngữ: “mênh mông biển lúa” => nhấn mạnh không gian rộng lớn của cánh đồng

+ So sánh “đâu trời đẹp hơn” => lòng tự hào về đất nước VN

ta có: x + (1 + 2 + 3 + 4)=110

Vậy 110 - (1 + 2 + 3 + 4)=100

x=100

Quãng đường xe đi khi bánh sau xe lăn được 180 vòng:

\(152,4\times180=27432\left(cm\right)=274,32\left(m\right)\)

Đổi 121,92cm = 1,2192m

Số vòng bánh trước quay khi bánh sau quay 180 vòng là:

\(274,32\div1,2192=225\left(vòng\right)\)
