Transcript text: 8. A board that is 22 inches long is cut into two pieces. The longer piece is 4 inches longer than the other piece. How long are the pieces?
Solution
Find the lengths of the two pieces of the board.
Define variables
Let's define:
$x$ = length of the shorter piece (in inches)
$x + 4$ = length of the longer piece (in inches)
Set up an equation based on the total length
The total length of the board is 22 inches, so:
$x + (x + 4) = 22$
Solve the equation
$x + x + 4 = 22$
$2x + 4 = 22$
$2x = 18$
$x = 9$
Therefore:
Shorter piece = $x = 9$ inches
Longer piece = $x + 4 = 9 + 4 = 13$ inches
\(\boxed{\text{The pieces are 9 inches and 13 inches long}}\)
\(\boxed{\text{The pieces are 9 inches and 13 inches long}}\)
