Question

Compare the two expressions using an inequality symbol. Prove it by showing all working. 1. 23 +5×3_____2+8(35÷7)2. 9×(−2)−(−4)2_____34÷9+2×53. 5×22 −23(−6+3)_____6(2+9)−33 ÷9−4

Answer 1

$\begin{gathered} 23+5\times3\text{\_\_\_\_\_\_}2+8(35\div7)_{} \\ 23+15\text{\_\_\_\_\_\_}2+8(5)_{} \\ 38\text{\_\_\_\_\_\_}2+40 \\ 38\text{\_\_\_\_\_\_}42 \\ 38<42 \\ \text{Therefore,} \\ 23+5\times3<2+8(35\div7)_{} \end{gathered}$
