Question

Найди значения выражений b +20, 14+b, 80-b, b-9 при b=70, b=23, b=11

Answer 1

70 + 20 = 90
14+70 = 84
80 - 70 = 10
70 - 9 = 61

23 + 20 = 46
14 + 23 = 37
80 - 23 = 57
23 - 9 = 14

11 + 20 = 31
14 + 11 = 25
80 - 11 = 69
11 - 9 = 2

Answer 2

  b=70
70+20=90  14+70=84  80-70=10  70-9=61
  b=23
23+20=43  14+23=37  80-23=57  23-9=14
  b=11
11+20=31  14+11=25  80-11=69  11-9=2
