<u><em>The correct answer is: </em></u>4.2 inches.
<u><em>Explanation</em></u><span>
<u><em>: </em></u>We use the size of the largest dimension of the reproduction to find the scale factor. The largest dimension of the original drawing was 5 inches.
The largest dimension of the reproduction is 11 inches.
<u>To find the scale factor, divide: </u>
</span></span>

<span><span>=2.1.
Since the scale factor is 2.1, to find the smallest dimension of the reproduction we <u>multiply the original by 2.1</u>:
2*2.1=4.2 inches.</span></span>
The answer is D. Because (18 x 10^6) + (5 x 10^4) = 18050000. And the answer to 1.805 x 10^7 also equals 18050000, if you do the math.
For the equation -1/2x+3y=-3
the x-intercept=6
the y-intercept=-1
5 equals 5/1. Simple as that.
