2) 1.2 x 10,000 - 1.5 x 1,000 - 2.2 x 100 = 10,280
3) 7.3 x 100,000 + 1.6 x 1,000,000 + 4.7 x
100,000 = 2,800,000
4) 8.2 x 10,000 - 2.4 x 10,000 - 1.5 x 1,000 = 56,500
5) 2.4 x 1,000 + 3.4 x 10,000 + 1.5 x 1,000 = 37,900
6) 6.2 x 10,000 - 3.4 x 100 - 7.5 x 1,000 = 54,160
7) 8.3 x 100,000 + 1.6 x 10,000,000 + 6.7 x 10,000 = 16,897,000
8) 8.0 x 1,000 - 0.8 x 1,000 - 1.2 x 100 = 7,080
Answer:
x = 12, sides = 23
Step-by-step explanation:

Since
is equilateral, all three sides are equal. Therefore:
![\left[\begin{array}{l}y=2x-1\\y=5x-37\\y=x+11\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bl%7Dy%3D2x-1%5C%5Cy%3D5x-37%5C%5Cy%3Dx%2B11%5Cend%7Barray%7D%5Cright%5D)
Substituting y = x + 11:
![\left[\begin{array}{l}x+11=2x-1\\x+11=5x-37\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bl%7Dx%2B11%3D2x-1%5C%5Cx%2B11%3D5x-37%5Cend%7Barray%7D%5Cright%5D)
Solving for x:

Substituting x = 12:

Thus, <em>x</em> = 12 and the length of each side is 23.
