So 0.5 ft per day is the same as 0.5 ft per 24 hours. This equals 0.5/24 ft an hour. 0.5 ft /24=0,02083 ft. Simple conversion yields 0.02083*12=0.25. So the vine can grow by .25 inches per hour.
Answer:
Depending on how they want the answer, it's 
gallon or 
gallon or 1.43 gallon. Those numbers are the same just in fraction, mixed fraction or decimal form.
Step-by-step explanation:
2/7 times 5 = 10/7
The equation
(y + 5) + y = 6
shows the substitution method being used to solve the system of linear equations. So the correct option among all the options given in the question is option "D".
For a better explanation, let us first write down the two equations given in the question.
x + 5 = 6
and
x = y + 5
Now the thing that has been done is that the value of x in the first equation has been replaced by the value of x that is given in the second equation. this is actually the substitution method of solving equations.
What do you need help with
You would need to know the cost of the box of 20, then you would divide the total cost by the number of pencils in the box. This would give you the cost of one pencil - which is the unit cost.
Example:
Lets say the box of 20 pencils cost $10.
Divide the total cost by the number of pencils:
10 / 20 = 0.50 - This means each pencil cost 50 cents, so the unit cost would be 50 cents per pencil.
