Question

12×2+3×2-8×2+5×2-7×2​

Answer 1

Respuesta:

(12)(2)+(3)(2)−(8)(2)+(5)(2)−(7)(2)

=24+(3)(2)−(8)(2)+(5)(2)−(7)(2)

=24+6−(8)(2)+(5)(2)−(7)(2)

=30−(8)(2)+(5)(2)−(7)(2)

=30−16+(5)(2)−(7)(2)

=14+(5)(2)−(7)(2)

=14+10−(7)(2)

=24−(7)(2)

=24−14

=10

Answer 2

Hola, que tal!!

RESOLVEMOS:

A=(12)(2)+(3)(2)−(8)(2)+(5)(2)−(7)(2)

1-Multiplicaciones y divisiones

2-sumas y restas

A =24+(3)(2)−(8)(2)+(5)(2)−(7)(2)

A =24+6−(8)(2)+(5)(2)−(7)(2)

A =30−(8)(2)+(5)(2)−(7)(2)

A =30−16+(5)(2)−(7)(2)

A =14+(5)(2)−(7)(2)

A =14+10−(7)(2)

A =24−(7)(2)

A =24−14

A =10

Rpta:  El número es 10
