Answer:
8
Step-by-step explanation:
Isolate and solve for C
![c + (-20) = -12\\c - 20 = -12\\c = -12+20\\c = 8](https://tex.z-dn.net/?f=c%20%2B%20%28-20%29%20%3D%20-12%5C%5Cc%20-%2020%20%3D%20-12%5C%5Cc%20%3D%20-12%2B20%5C%5Cc%20%3D%208)
Answer:
2002 pounds
Explanation:
To know the weight of the plane, we need to find an equation that relates the amount of fuel to the weight.
This equation can be founded using the following
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
Where m is the slope, x1 is the number of gallons and y1 is the respective weight. So, replacing m = 6.0, x1 = 51 gallons and y1 = 2206 pounds, we get:
![y-2206=6(x-51)](https://tex.z-dn.net/?f=y-2206%3D6%28x-51%29)
Now, we can solve for y
![\begin{gathered} y-2206=6(x)-6(51) \\ y-2206=6x-306 \\ y=6x-306+2206 \\ y=6x+1900 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20y-2206%3D6%28x%29-6%2851%29%20%5C%5C%20y-2206%3D6x-306%20%5C%5C%20y%3D6x-306%2B2206%20%5C%5C%20y%3D6x%2B1900%20%5Cend%7Bgathered%7D)
Then, we can calculate the weight of an airplane with 17 gallons of fuel replacing x = 17 on the equation above
y = 6x + 1900
y = 6(17) + 1900
y = 102 + 1900
y = 2002
Therefore, the answer is 2002 pounds
The answer is D. 200m = 2cm. That's because to get from meters to centimeters, you need to multiply by 100. 200 * 100 is not 2, therefore D is the answer.
