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.
Answer:
Step-by-step explanation:
-13 = 5(1+4m)-2m
-13=5+20m-2m
-13=5+18m
-13-5=18m
(-13-5)/18=m
Total = Principal * e^(rate*years)
where "e" is the mathematical constant 2.71828182828459
Total = 1,600 * e(.046*4)
Total = 1,600 * 2.71828182828459^(.184)
Total = 1,600 *
