The answer is 63/1, so basically 63 is your answer.
To show my work all u have to do is divide 378/6 and get 63, divide 6 by 6 and u get 1, simplify it and u get 63. How did I get 6 in the first place? I found the gcf( greatest common factor) of both 378 and 6, then I simplified the fraction by dividing both numerator and denominator and got 6.
Hope this helps and if it does, don't forget to mark as brainliest.
10.39 is the measure of angle C.
2/3 box per 1/2 minute => 2(2/3) box per 2(1/2) minute
Thus it is 4/3 box per minute
