y=-1/2x+6
Step-by-step explanation:
<span>Correct answer: B
The first thing to be done is to convert the 2 tons into pounds.
1 pound is equal to 0.0005 tons (US). So, 2 tons divided by 0.0005 will give us the aluminium pounds per week that are processed by the Recycling Centre B.

=4000
<span>Recycling Centre B processes 4000 pounds/week. In order to compare to Recycling Centre A, we need to find the rate in pounds per hour. To do so divide the 4000 pounds by 168 (24</span>×7 = number of hours in a week).

≈23.8
The Recycling Centre B processes about 23.8 pounds/hour whereas the Recycling Centre A processes 100pounds/hour.
The answer is C, t-19=-12. This is because the temperature decreased from t by 19 degrees and ended up at -12 degrees. Hope this helped!
