Answer:

\frac{6}{7} x -  \frac{2}{5} y +  \frac{5}{7} (y + x) \\  = ( \frac{6}{7}  +  \frac{5}{7} )x + ( \frac{5}{7}  -  \frac{2}{5} )y \\  =  \frac{11}{7} x +  \frac{15}{35} y \\  =  \frac{11}{7} x +  \frac{3}{7} y \\  =  \frac{1}{7} (11x + 3y)

Helga [31]

Answer:

5 hours and 40 minutes would be class

Step-by-step explanation:

We know that the total time is 7 hours, which in minutes would be:

7 * 60 = 420

420 minutes would be class, now, we subtract the other times that are not to be in class and it would be:

420 - 30 - 50 = 340

So we could say that in class it takes 340 minutes, and if we spend hours it would be:

340/60 = 5.67 hours or also 5 hours and 40 minutes would be class.
