Answer:
Max exercises 13 hours a week, and Sasha 7.
Step-by-step explanation:
To find the number of hours each of them exercises during the week, we solve the system of equations.
In the second equation:
Replacing in the first equation:
So Sasha exercises 7 hours per week.
Max:
Max exercises 13 hours a week.
(5/6 + 2/3 + 1/2)/3 = 2/3 = 0.66

Answer:
-(18/49)=n or approximately n=-0.367
Step-by-step explanation:
our equation is: m(nx²-y)/z=5n in order to find n we need to substitute the values given in the question. when we substitute we get:
6*(n*(-2)²-(-3))/(-5)=5n
6(4n+3)/(-5)=5n (we distribute the 6 in the numerator)
24n+18/-5=5n (we multiply both sides by (-5))
24n+18=-25n (we subtract 24n from both sides)
18=-49n (divide both sides by (-49))
-(18/49)=n or approximately n=-0.367
