The time to fill the sink if Blake forgets to put in the stopper would be 15 mins.
Step-by-step explanation:
Given that,
The kitchen sink can fill in: 6 mins
The sink can drain in: 10 mins
We have to find the time to fill the sink if Blake forgets to put in the stopper. For that,
Lets say, the full tank = 1
Filling rate = 
Drainage rate = 
Hence, the time to fill the tank would be:

(Multiply by LCM)


x = 15
Hence, the time to fill the sink if Blake forgets to put in the stopper would be 15 mins.
Answer:
Step-by-step explanation:
The fractions need a common denominator before you can add them together.
The least common denominator is 15bc.
Answer:
Ashley would have to pay an additional $608.52 in interest when the length of the loan changes from 3 years to 5 years.
Step-by-step explanation:
Although the problem gives us the initial amount of the balance ($4000) and the interest rate (13%), we are really only concerned with the total amount Ashley will make in payments in three years versus five years. If she pays $134.78 for three years, that is 36 months, or $134.78 times 36 which is equal to $4852.08. However, if she decides to take longer to pay it and instead pays $91.01 for five years, or 60 months, then her total amount paid would be $5460.60. To find the difference between these two, simply subtract $5460.60-$4852.08 to get $608.52.
2x+4y=12 ------>1
y=1/2x-3. ------->2
2 into 1
2x+4(1/2x-3)=12
2x+2x-12=12
4x-12-12=0
4x-24=0
4x=24
x=24/4
x=6 ------> 3
3 into 2
y=1/2x-3
y=1/2(6)-3
y/=0
