Answer:
Total weight of the nuts bought by Dan = 5.4 kg
Explanation:
Number of packets of nuts bought by Dan = 24
Weight of each packet of nuts = 225g
Total weight of the nuts bought by Dan = Number of packets of nuts bought by Dan * Weight of each packet of nuts
Total weight of the nuts bought by Dan = 24 * 225 = 5400 g = 5400/1000 kg = 5.4 kg
Total weight of the nuts bought by Dan = 5.4 kg
If the perimeter is 98 cm, the sum of the lengths of two adjacent sides is 49 cm.
... (2x -1) + (3x +5) = 49 . . . . use the given information and relation
... 5x +4 = 49 . . . . . . . . . . . simplify
... 5x = 45 . . . . . . . . . . . . . . . subtract 4
... x = 9 . . . . . . . . . . . . . . . . . divide by 5
The left side dimension is then
... 2x -1 = 2·9 -1 = 17 . . . . cm
The top dimension is
... 3x +5 = 3·9 +5 = 32 . . . . cm
The rectangle is 17 cm by 32 cm.
