Question

Вычислите значения выражения при m+n=35. (m+15)+n; (m+7)+n; (m+48)+(n+20); (m+26)+(n+14); m+(n+9); (m+30)+(n+17).

Answer 1

при m + n = 35:

(m + 15) + n = 15 + (m + n) = 15 + 35 = 50

(m + 7) + n = 7 + (m + n) = 7 + 35 = 42

(m + 48) + (n + 20) = (48 + 20) + (m + n) = 68 + 35 = 103

(m + 26) + (n + 14) = (26 + 14) + (m + n) = 40 + 35 = 75

m + (n + 9) = (m + n) + 9 = 35 + 9 = 44

(m + 30) + (n + 17) = (m + n) + (30 + 17) = 35 + 47 = 82
