The figure description helps; Choice A; by showing that a triangle cannot be formed when the sum of the lengths of two sides is less than the length of the third side.
<h3>What is the triangle inequality theorem?</h3>
The triangle inequalities theorem postulates that the sum of lengths of two sides of a triangle must be greater than the length of the third side.
On this note, it follows that the since the sum of sides given in the description 7 and 4 is less than 15, the segments cannot be used to form a triangle.

The speed of the airplane = 2951 / 6.5 = 454 mph
Answer:
Step-by-step explanation:
x = 15 cent stamps
y = 20 cent stamps
I will be using these equations
x + y = 16
0.15x + 0.20y = 3
x = 16 - y
0.15(16 - y) + 0.20y = 3
2.40 - 0.15y + 0.20y = 3
-0.15y + 0.20y = 3 - 2.40
0.05y = 0.60
y = 0.60/0.05
y = 12.......there were 12 twenty cent stamps
x + y = 16
x + 12 = 16
x = 16 - 12
x = 4.....there were 4 fifteen cent stamps
no change is received

Equations can be solved in several ways; one of these ways is the graphical method.
The number of commercials, x, and the number of movies, y, on which Naomi's songs were played are 5 and 2, respectively.
Let:
<em />
<em> commercials</em>
<em />
<em> movies</em>
<em />
She earned a total of $300.
This is represented as:

Her songs were played on 3 more commercials than movies.
This is represented as:

See attachment for the graphs of


From the graph, the lines of both equations intersect at:


This means that:
- <em>The number of movies is 2</em>
- <em>The number of commercials is 5</em>
