1- Diante da expressão, sendo x= 2-5 e y=2-2 . Os alunos do 8 ano do colégio Santana Lima, Nicolas

e Rudinei optam por resolvê-la de maneiras diferentes. Nicolas decide subtrair os valores de x e y na

expressão para em seguida resolvê-la, enquanto Rudinei prefere simplificar ao máximo a expressão,

utilizando conceitos que aprendeu em anos anteriores, para só então fazer a subtração.

Escolha um dos métodos de resolução e responda o problema.

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
