To solve this problem, we need to determine the value of x, which represents the number of thermoses Genevieve drank.
Let's break down the information given:
Total amount of coffee: 4.5 gallons
Number of thermoses: 18
Amount of coffee drank by Genevieve: 6 pints
We know that 1 gallon is equal to 8 pints. So, 4.5 gallons is equal to 4.5 * 8 = 36 pints.
We can set up the equation as follows:
Amount of coffee drank by Genevieve = Total amount of coffee / Number of thermoses * Number of thermoses drank by Genevieve
6 pints = 36 pints / 18 * x
Let's simplify and solve for x:
6 = 2 * x
To isolate x, we divide both sides of the equation by 2:
6 / 2 = x
3 = x
The value of x is 3. Genevieve drank from 3 thermoses.
#### 3
The answer is: 3
