the temperature in a room rises 1 F every 3 minutes. When the scientist enters the room, it is 50 F. a) write the equation b) what will be the temperature after 21 minutes? c) when will the temperature be 55 F ?

equation is y= 50 + 3f

57F

15 Minutes

Step-by-step explanation:

a) the equation above because 50 is the starting temp and every 3 minutes is another degree F

b) if the temp rises 1 degree every 3 minutes, then 21/3 is 7 degrees hotter plus 50, which is 57 F.

c) if 50 plus 3f is the equation, then 3 times 5 will make 55 degrees. After 15 minutes, the temp will be 55 F.
