The mean temperature for the first 4 days in january was 7°c. the mean temperature for the first 5 days in january was 9°c. what was the temperature on the 5th day?

add an image !

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i

any of them that add up to 180 degrees.
