Let's call the number of rows 'R' . (Clever ?)
There are (3x -2) trees in each row, and there are 'R' rows,
so the total number of trees is [ R times (3x-2) ].
But the problem told you that the total number of trees is (24x-16).
So
R(3x - 2) = (24x - 16)
For a quick, happy ending, how about factoring '8' out of the right side:
R(3x - 2) = 8(3x - 2)
Is it jumping out at you yet ?
If not, then divide each side by (3x - 2) :
<em> <u> R = 8</u></em>
There are eight (8) rows of trees.
For the answer to the question above, I'll show my solution on how you can solve your problem.
AC² + BC² = AB²
<span>5² + 12² = AB² </span>
<span>25 + 144 = AB² </span>
<span>169 = AB² </span>
<span>13 = AB </span>
<span>Triangle ABC is proportional to triangle ADB. </span>
<span><u>AC </u>= <u>AB </u></span>
<span>AB AD </span>
<span><u>5</u> = <u>13 </u></span>
<span>13 AD </span>
<span>5AD = 169 </span>
<span>AD = 169/5 </span>
<span>AD = 33.8 </span>
<span>AD = AC + CD </span>
<span>33.8 = 5 + CD
</span>So the answer is
<span>CD = 28.8 </span>
Answer:
105

1 gal 2 qts 3 pts
1 gal 3 qts 7 pts
1 gal 3 qts 3 pts
---------------------------add
3 gal 8 qts 13 pts
1 pt = 0.5 qts...so 12 pts = 12* 0.5 = 6...so now we have :
3 gal 14 qts 1 pt
1 qt = 0.25 gal..so 12 qts = 12 * 0.25 = 3 gallons...so now we have :
6 gal 2 qts 1 pt <===
