Answer: hours
Step-by-step explanation:
Let x be the time ( in hours ) you feel good and y be the time ( in hours ) that you get tired.
As per given , we have
x+y= 8
Since :
So , we have
20x+12y=122
According to the given question , we have the following system of equations ,
Multiply 12 on both sides of equation (1) , we get
Eliminate equation (3) from (2) , we get
Hence, you felt hours good.
Hi!
The answer is :
(y+2) * (y+9) = y^2 + 2y + 9y + 18 = y^2 + 11y + 18
Hope this helps!
