The answer you want would be -120
b/c 200/5 is 40 so -3*40 is <em>-120</em>
Y = k/x
13 = k/6
k = 78
y = k/x
8 = 78/x
8x = 78
x = 78/8
x = 9.75
If two triangles are similar then the
corresponding sides are in proportion. Thus,
AB / AU = BC / UV = AC / AV
AB / (20x+108) = 703 / 444
Where AB is equivalent to:
AB = AU + UB
AB = 20x + 108 + 273
AB = 20x + 381
Therefore going back to the first equation:
(20x + 381) / (20x + 108)
= 703/444
444 (20x + 381) = 703 (20x + 108)
8880x + 169164 = 14060x + 75924
14060x - 8880x = 169164 – 75924
5180 x = 93240
x = 93240 / 5180

Q2) 58.08
Q3) I got 180 but not sure.
Q4) I got 138
Q5) I got 28.56 for this one.
Hope this helps.
There are no equations there. Only two functions of x.
