Question

Stiind ca :
m+5+n+7+p+9=31
determina 2018+m+n+p​

Answer 1

2018+m+n+p

31-9-7-5=10

m+n+p=10

2018+10=2028

Answer 2

Răspuns:

Explicație pas cu pas:

m + 5 + n + 7 + p + 9 = 31

m + n + p + ( 5 + 7 + 9 ) = 31

         → adunarea este asociativa

m + n + p + 21 = 31

m + n + p = 31 - 21

m + n + p = 10

______________

2018 + m + n + p = 2018 + 10 = 2028
