60 + 60 + 60 + 50 + 50 + 40 + 30 = 350
10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150
286
40
The answer is: 20/2 plus 30 = 40
50 + 40 + 40 + 40 + 30 + 30 + 20 + 10 = 260
40 + 57 + 40 + 30 + 47 + 31 + 60 + 38 + 64 + 30 + 120 = 557
2+40+30=72
30
40+-30=10
30 + (30-10) = 50
30 + 50 + 40 = 120 centimetres.
40% + 30% = 70%
60 + 60 + 60 + 50 + 50 + 40 + 30 = 350
10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150
-40 + 70 = 30
The sum of these numbers is 563.
