verifica egalitatile scriind A (adevarat)sau F(fals). 100-5x7-42:7=5x10+9?

Răspuns :

[tex]100 - 5 \times 7 - 42 \div 7 = 5 \times 10 + 9[/tex]

[tex]100 - 35 - 6 = 50 + 9[/tex]

[tex]65 - 6 = 59[/tex]

[tex]59 = 59 \: (A)[/tex]
100 - 5 * 7 - 42 : 7 = 5 * 10 + 9
100 - 35 - 6 = 50 + 9
65 - 6 = 50 + 9
59 = 59 (A)
