Answer:
4 hours
Step-by-step explanation:
We know that there are 24 hours in a day. Therefore, we will subtract from 24.
If mark spends one-third of his day sleeping, then he will be asleep for 8 hours.
We also know that if Mark spends one-sixth of his day at soccer practice, he will have been practicing for 4 hours.
We now simply subtract from 24:
Therefore, Mark will have 4 hours of free time.
Nickels n
quarters q
I: 3.15=n*0.05+q*0.25
II: n+q=23
isolate n in II:
n+q=23
n=23-q
substitute n in I:
3.15=n*0.05+q*0.25=
3.15=(23-q)*0.05+q*0.25
3.15=(23-q)*(1/20)+(q/4)
3.15=(23/20)-q/20+(q/4)
3.15=1.15-(4*q/20)
2=q/5
10=q
insert q=10 into II:
n+q=23
n+10=23
n=13
so c) 3 more nickels than quarters
