The temperature at the beginning of the day was 3°C. The temperature dropped 12°C by the end of the day. What was the temperature at the end of the day? Use the number line model to find 3-12. ​

3 - 12 = -9°C

So the temperature in the end of the days was -9°C

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
