Answer:
w < 8 meters ( w must be greater than 0 because length cannot be 0)
Step-by-step explanation:
One side with building is 23 meters, the other opposite side also will be 23 meters (with rope).
Let width (remaining 2 sides) be "w", he has AT MOST 39 meters of rope, so we can write:
Rope Needed = 23 + 2w < 39
Simplifying:

The range of possible values of w is
meters (of course w has to be greater than 0)
It is 32.8 I just did %in my class today
Answer:

Step-by-step explanation:
The amount of children's tickets is x, while the amount of adults' tickets is 2x
5.1*x- the amount of money from children
9.6*2x= 19.2x- the amount of money from adults
5.1x+19.2x= 558.9
x=23 - child tickets
