Question

amistre64 · Answer

f +s +l = 280

s = 2f-10

l = 4(s) = 4(2f-10) = 8f -40

f + (2f -10) +(8f -40) = 280

11f -50 = 280

11f = 330

f = 30
----------------

s = 2(30)-10 = 60 - 10

s = 50
------------------------

l = 4(50)

l = 200
-------------------

30 + 50 +200 = 280

80 + 200 = 280

280 = 280
