Answer:
Step-by-step explanation:
To navigate through this problem, start by finding how much each senator can complete in a fixed amount of time. I'll choose 10 as it's the greatest common factor of 30 and 50.
In 10 minutes, the junior senator can complete 
of the labyrinth.
In 10 minutes, the senior senator can complete 
of the labyrinth.
Therefore, working together, they can complete 
of the labyrinth in 10 minutes. Thus, it will take them 
to complete one labyrinth.
The amount of time it take them to complete 12 labyrinths is then 
Answer:
The system has no solution
Step-by-step explanation:
Encountering an incorrect mathematical statement anywhere within the solution such as
1 = 3 which of course is false
Indicates the system has no solution
Answer:
50 degrees.
Step-by-step explanation:
Angle FGE = 
because angles on a straight line add up to 180 degrees.
Angle EFG = 
(Angles in a triangle add up to 180)
Add 20 to both sides:
Subtract 6x from both sides:
Angle 
"<span>5 to the negative 4th power over 5 to the 3rd</span>" translates to
5⁻⁴ / 5³
So you can just combine exponents.
5⁻⁴ / 5³ = 5⁻⁴ ⁻ ³ = 5⁻⁷ = 1/5⁷
Final answer: 1/5⁷
