Answer:
The length of the shortest piece is 11 inches. The length of the medium piece is 14 inches. The length of the longest piece is 20 inches.
Step-by-step explanation:
Ok, so we have a long sandwich of 45 inches that will be divided in 3, giving us the following formula (x = shortest, y = medium, z=longest):
x + y + z = 45
Then we have middle piece (y) is 3 inches longer than the smallest (x):
y = x + 3
And the shortest piece (x) is 9 inches shorter than the longest (z):
x = z - 9 or z = x + 9
Let's place the found values of y and z in the first equation:
x + y + z = 45
x + (x + 3) + (x + 9) = 45
3x + 12 = 45
3x = 33
x = 11
So, x = 11, y = 14 and z = 20. (11 + 14 + 20 = 45).

Answer is: 49
<h3>All options satisfies the given inequality</h3>
<em><u>Solution:</u></em>
Given that,
Here, modulus means that, the absolute value of a number is never negative
<em><u>Option A</u></em>
Substitute x = 2 and y = -9 in given
-9 is less than 7 is true
This forms a solution to given inequality
<em><u>Option B</u></em>
(-4, 12)
Substitute x = -4 and y = 12 in given
12 is less than 37 is true
This forms a solution to given inequality
<em><u>Option C</u></em>
(3, 15)
Substitute x = 3 and y = 15 in given
15 less than 46 is true
This forms a solution to given inequality
<em><u>Option D</u></em>
(0, 0)
Substitute x = 0 and y = 0 in given
0 is less than 1
This forms a solution to given inequality
