Answer:
The number of days in which the amount in warehouse #2 is 1.2 greater than warehouse #1 is 6 days.
Step-by-step explanation:
Let
x: number of days
y: amount of potatoes
We can express the amount of potatoes in each warehouse using linear equations:
Warehouse #1:
Warehouse #2:
We need to find the value of x when
Substituting the expressions for y1 and y2 in :
Applying distributive law:
Solving the equation by subtracting 108x and 180 on both sides:
Now we divide by 12 on both sides:
Therefore, the number of days in which the amount in warehouse #2 is 1.2 greater than warehouse #1 is 6 days.
Answer:
Step-by-step explanation:
Let's solve this problem step-by-step. The library had 1,500 books in 2011. The ratio of books in 2011 and in 2012 is 1:2. Therefore, let the number of books in 2012 be .
We have the following proportion:
Therefore, there were 3,000 books in 2012. The ratio of books in 2012 and in 2013 is 2:5. Let the number of books in 2013 be .
We have:
Therefore, there were 7,500 books in 2013.
