Step-by-step explanation:
Answer: Let c represents the time spends in producing a cockpit and p represents the time spends in producing a propulsion system. Thus, According to the question, Machine A ran for 26 hours and produced 4 cockpits and 6 propulsion systems.⇒ 4 c + 6 p = 26And, Machine B ran for 56 hours and produced 8 cockpits and 12 propulsion systems,⇒ 8 c + 12 p = 56Hence, the system of equations that will be used to find a unique amount of time that it takes each machine to produce a cockpit and to produce a propulsion system is,4 c + 6 p = 26, 8 c + 12 p = 56But both lines are parallel,Hence there is no solution of this system,Therefore, we can not solve for a unique amount of time that it takes each machine to produce a cockpit and to produce a propulsion system.
The answer would be D because 3.991 x 10(to the fifth power) is 399,100, which is the answer to the expression
