tl=x+7, lc=2x-3, and tc=25, find tl and lc.
So we have
(x + 7) + (2x - 3) = 25 combine like terms
3x + 4 = 25 subtract 4 from both sides
3x = 21 dviide both sides by 3
x = 7
So..... tl = (7) + 7 = 14 ....and.......lc = 2(7) - 3 = 14 - 3 = 11
I don't know why CPhill assumed that tl + lc = tc; in fact, under this assumption, x = 7, but
t reduces to √(350/11) ≈ 5.14
c reduces to (25√11)/√350 ≈ 4.432
l reduces to (11·√350)/(25·√11) ≈ 2.48
so l isn't between t and c.
Unfortunately, I don't know a possible answer.
