We know that the wall is 12 ft. long and the bed is 6.5 ft. long. This means there is (12 - 6.5) = 5.5 ft. of space left on the wall for the dresser.
Since we want to find the maximum length of the dresser that can fit, we need to add the 5.5 ft. of space to the length of the bed:
l + 6.5 ≤ 12
Subtracting 6.5 from both sides, we get:
l ≤ 5.5
So the answer is:
d. l−6.5≤12
The wall of a bedroom is 12 ft. long. A bed 6.5 ft. in length is already along the wall. Which inequality shows the length (l) of a dresser that can also be placed against the wall?
a. l−6.5≥12
b. l+6.5≤12
c. l+6.5≥12
d. l−6.5≤12
