The two numbers are illustrations of system of equations
The two numbers are 2.7 and 37.3
<h3>How to determine the two numbers?</h3>Let the numbers be x and y.
So, we have the following equations
x + y = 40
xy = 100
To determine the value of the variables, we simply plot the graph of both equations
From the graph, we have the following result
(x,y) = (2.7, 37.3)
Hence, the two numbers are 2.7 and 37.3

Lets name the shortest piece a, the medium b and the longest c
Together they are 90inches
The longest is 30 inches longer than the shortest
The third piece is half the lenght of the longest
So if you place c=a+30 in the other 2 equasions you get
And
Now if you put this 2 toghether u get
Multyplied by 2
Meaning that a=18inches
Now that we have the lenght of a we put it in the previous equasion
So b=48/2 which means b=24inches
And together they must be 90 so
C=48inches
