Answer:
Step-by-step explanation:
Notice that in the second equation, the coefficient of 
is 
times greater than in the first. Therefore, by making the coefficient of 
in the second equation times greater than in the first, it's impossible to only isolate one variable.
Therefore, when 
, there are no solutions to this system.
Answer:
C
Step-by-step explanation:
It would take 90 degree to rotate clockwise so it will take 360-90=270 degree to rotate counterclockwise
Answer:
Yes
Step-by-step explanation:
90% of 50 is 40 so if more than 40 left before it hit 60 seconds then the 90% has been achieved.
It will become "Add a number times 6 to 5."
