Answer:
33 inches
Step-by-step explanation:
The question above can be solved by using "algebraic expressions."
Let x be the length of the shorter piece.
Let 2x be the length of the longer piece.
Let's solve.
- x + 2x = 99 (inches)
- 3x = 99
- x = [tex]\frac{99}{3}[/tex]
- x = 33
The length of the shorter piece is 33 inches.
Let's get the length of the longer piece.
- 2x = ?
- 2(33) = 66
The length of the longer piece is 66 inches.
Let's check.
x + 2x = 99 inches
33 + 66 = 99
99 = 99
The answer is correct.
