I don't really know if the question is complete but...
y = x -10 can be a solution
so y would be -7 when x is 3
I am pretty sure it is 0.064. Hope this helps
Answer:
640
Step-by-step explanation:
32 *20
Temperature after 20 minutes is found by multiplying-2.5 by 20 since it goes down by 2.5 degrees for one minute. -2.5 * 20 = -50. Adding this to 180.3 will give the temperature 130.3 degrees.
