Question

1. a piece of material measures 38.25 inches. courtney cuts the piece of material into two pieces. one piece measures 19.5 inches. write an addition equation that could be used to find the length of the other piece of material. (example 1)

Explanation:

Step1: Define variable for unknown length

Let $x$ = length of the other piece (in inches).

Step2: Set up addition equation

Total length = sum of two pieces
$$38.25 = 19.5 + x$$

Step3: Solve for $x$

Subtract 19.5 from both sides:
$$x = 38.25 - 19.5$$
$$x = 18.75$$

Answer:

Addition equation: $\boldsymbol{19.5 + x = 38.25}$
Length of the other piece: $\boldsymbol{18.75}$ inches
