Answer:
5 degrees colder
Step-by-step explanation:
You take the starting point then subract the ending point and you get your answer. But in order to know if its colder or warmer is to know that the higher the number, the hotter, and the lower the number, the colder.
= 16 + 49 - 3(11) - 4(10)
= 16 + 49 - 33 - 40
= -8
Well 22/7 is 3.14 and so on but since there is a little more than 3 you need to make sure he covers up all the fencing places... SO John will need 4 fences
1...2...5...10 are the factors of 20 that go into 50.
