Answer:
[tex]5x + 2\frac{1}{2} = 15[/tex] and [tex]\frac{15 - 2\frac{1}{2} }{5}[/tex]
Step-by-step explanation:
Assume the length of each piece of wood is x feet.
We can say that the length of uncut board = (number of pieces × length of each piece) + length of leftover board, or [tex]15 = 5x + 2\frac{1}{2}[/tex].
Apply the Symmetric Property of Equality:
[tex]5x + 2\frac{1}{2} = 15[/tex]
Subtract [tex]2\frac{1}{2}[/tex] from both sides of the equation:
[tex]5x = 15 - 2\frac{1}{2}[/tex]
Divide both sides by 5: (See image)
Cancel out the common terms from the numerator and denominator:
[tex]x = \frac{5}{2}[/tex]
[tex]= 2\frac{1}{2}[/tex]
