Answer 1

9514 1404 393

Answer:

  321.25 kg

Step-by-step explanation:

The given relations are ...

  b = 2s

  4b +4s = 771

Substituting for b, we have ...

  4(2s) +4s = 771

  12s = 771

  s = 64.25

  b = 2s = 128.50

Then the weight of interest is ...

  b +3s = 128.50 +3(64.25) = 321.25 . . . . kg
