Answer:
The top shelf is 5 feet, the middle shelf is 5.5 feet and the bottom shelf is 9.5 feet
Step-by-step explanation:
Let t= length of the top shelf, m = length of middle shelf and b = length of bottom shelf.
Therefore:
t = m - 1/2; m = t + 1/2
Also, b = 2t - 1/2
The total of the three shelves is 20 feet, therefore:
t + m + b = 20
Substituting:
t + t + 1/2 + 2t - 1/2 = 20
4t = 20
t = 20/4
t = 5 feet
m = t + 1/2 = 5 + 1/2 = 5.5 feet
b = 2t - 1/2 = 2(5) - 1/2 = 9.5 feet
The top shelf is 5 feet, the middle shelf is 5.5 feet and the bottom shelf is 9.5 feet

Answer:
A segment is called a perpendicular bisector of another segment if it goes through the midpoint and is perpendicular to the segment. While there can be many segments that bisect another segment, only one segment can be the perpendicular bisector.
Step-by-step explanation:
<em>perpendicular bisector</em>
The correct answer is0.5544
1- Can possibly be interpreted two ways:
(N - 7)/3 = 5
N-7 = 15 <-- multiplies both sides by 3
N = 15 + 7 = 22 <--- adds 7 to both sides
----------------------------------------------------
N/3 - 7 = 5
N/3 = 12 <--- adds 7 to both sides
N = 36 <--- multiplies both sides by 3
--------------------------------------------------------------------------
If the question were written:
"The quotient of the difference of a number and 7 is five, then
that will be the first case.
2-let x = the number
11 + 2x = 17
by solving we find:
x = 3
3- x=9
