Answer:
10
Step-by-step explanation:
Construct the equation
Let S=Sarah J=Jane
S=J+6
2J+3S = 68
Using substitution you can get
3(J+6)+2J = 68
5J + 18 = 68
5J = 50
J= 10
Answer:
5,840 minutes
Step-by-step explanation:
Assuming there are 365 days in a year. If finn brushes his teeth 3 times , for 2 min each time then the time spent to brush his teeth in a day
=3 * 2 minutes
= 6 minutes
If he flosses twice a day , for 5 minutes each time, then the time spent in a day to floss
= 2 * 5 minutes
= 10 minutes
Hence total time spent in a day brushing and flossing
= 6 + 10
= 16 minutes
Hence the time spent in a year brushing and flossing
= 16 * 365
= 5,840 minutes
