7 kg and 576 g or 7576 g
the "sum" means to add the numbers, therefore:98 + 126 = 224
126.
The sum of the first 450 consecutive odd numbers is 450 squared or 202,500.
450+250=700
730.
25 and 18 are a factor pair of 450 whose sum is 43.

The sum of the internal angles of a hexagon is (6-2)*180 = 720 degrees The four given angles add up to 53 + 126 + 89 + 117 = 385 degrees So the remaining two add up to 335 degrees.
Add all of the numbers together (find the sum of the set) 50 + 60 + 70 + 80 + 90 + 100 = 450. Then divide the sum by the amount of numbers in the set (6); 450 / 6 = 75.
41+42+43=126.
41+42+43 = 126
