<h3>
<em>Answer: 9 Cars</em></h3>
The answer to your question is 46.9
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

70 + 98 + 83 + 66 + 41 = 358
358 / 5 = 71.6
70 + 98 + 83 + 66 + 41 + 81 = 439
439 / 6 = 73.166...
Therefore, the correct answer to this problem is answer A.
