A thermometer reading 8 degrees is brought into a room with a constant temperature of 28 degrees. If the thermometer reads 13 degrees after 3 minutes, what will it read after being in the room for 5 minutes? For 10 minutes?

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
