You set the expressions equal to each other since they are congruent, then solve.
5x + 24 = 9x - 17
First subtract 24 from both sides to get
5x = 9x - 41
The subtract 9x from both sides to get
-4x = -41
Then divide both sides by -4 to get
x = 41/4 or as a decimal x = 10.25
Answer:
3 feet 10 inches
or
46 inches
Step-by-step explanation:
In order to determine the total length of the wood, convert 11 feet to inches
1 feet = 12 inches
11 x 12 = 132 inches
132 + 6 = 138 inches
If the length of each shelve is equal,
length of each shelve = 138 / 3 = 46 inches
or 46/12 = 3 feet 10 inches
