HELP PLEASE <br><br><br> Simplify.

maksim [4K]

Simplifying
2x + -3(3 * 0.6x + 2.7)

Multiply 3 * 0.6
2x + -3(1.8x + 2.7)

Reorder the terms:
2x + -3(2.7 + 1.8x)
2x + (2.7 * -3 + 1.8x * -3)
2x + (-8.1 + -5.4x)

Reorder the terms:
-8.1 + 2x + -5.4x

Combine like terms: 2x + -5.4x = -3.4x
-8.1 + -3.4x

You are cutting as many 20 1/2-inch pieces from the board to make

zlopas [31]

Answer: The number of steps you can make is 5 pieces and $\dfrac{35}{41}\ inch$ is left over.

Step-by-step explanation:

Since we have given that

Length of pieces from the board to make ladder steps for a tree fort = $20\dfrac{1}{2}\ inch=\dfrac{41}{2}$

Length of board = 120 inch

Number of pieces from the board to make ladder steps for a tree fort is given by

$120\div \dfrac{41}{2}\\\\=120\times \dfrac{2}{41}\\\\=\dfrac{240}{41}\\\\=5\dfrac{35}{41}$

Hence, the number of steps you can make is 5 pieces and $\dfrac{35}{41}\ inch$ is left over.
