Answer:
Step-by-step explanation:
- Time Spent Sleeping=7 hours
- Time Spent Studying=
of the day - Time Spent Travelling= of the day
There are 24 hours in a day, therefore:
- Time Spent Studying= X 24 =6 Hours
- Time Spent Travelling= X 24 =6 Hours
The total hour used for sleeping, studying and travelling=7+6+6=19 hours
Hours used for other things=24-19=5 hours
Therefore, the fraction of the day used for other things=
5m+2(m+8)+3
5m+2m+16+3
7m+19
Answer:
k=-1/5
Step-by-step explanation:
Factor and set each factor equal to zero.
Add 3 to both sides of the equation.
75k^2+30k+3=0
Factor 3 out of 75k^2+30k+3.
Factor using the perfect square rule.
Divide each term by 3 and simplify.
Set the 5k+1 equal to 0.
Solve for k.
