Me ajudem por favor Resolva As Expressões: 44) 15+(32÷4-3)= 45) 35÷(4×3-5)= 46) 7×(15÷3+5)=

Sabendo disso, vamos resolver as expressões dadas:

\[\eqalign{ & 44){\text{ }} \cr & 15 + \left( {32 \div 4 - 3} \right) = \cr & 15 + \left( {8 - 3} \right) = \cr & 15 + 5 = 20 \cr & \cr & 45) \cr & \cr & 35 \div \left( {4 \times 3 - 5} \right) = \cr & 35 \div \left( {12 - 5} \right) = \cr & 35 \div \left( 7 \right) = 5 \cr & \cr & 46){\text{ }} \cr & \cr & 7 \times \left( {15 \div 3 + 5} \right) = \cr & 7 \times \left( {5 + 5} \right) = \cr & 7 \times \left( {10} \right) = 70 }\]
