Answer:
Step-by-step explanation:
Let be 
and 
, we plot each curve with the help of graphic tool. In this case, we use Desmos and outcome is presented in the image attached below. Mathematically speaking, a solution to the system of equation exists when 
. Graphically speaking, it means that a solution exists when both curves pass through each other.
According to the graphic tool, we conclude that the only solution to the system of equations is .
Answer:
0.64, 65%, 2/3, 7/10.
Step-by-step explanation:
2/3=0.667

7/10=0.7
From least to greatest:
0.64, 65%, 2/3, 7/10
Subtract tchem both and wilk get the answer
102.62-101.94=0.68
