Answer: 720
Step-by-step explanation: to solve this problem, we do 15*8*12= 1440
this shape is half of that though, so we do 1440/2= 720, so the answer is 720
Answer:
The solution of the equation 
is 
.
Step-by-step explanation:
Let , we see that number of equation and variables are both the same and can be solved by algebraic means.
1) Given
2) 
Commutative property
3) ![x + [3+(-3)] = 11 + (-3)](https://tex.z-dn.net/?f=x%20%2B%20%5B3%2B%28-3%29%5D%20%3D%2011%20%2B%20%28-3%29)
Compatibility with addition/Associative property
4) Additive inverse/Modulative property/Definition of substraction/Result
The solution of the equation is .
This problem is about statistics. From December 17 to
December 24, there are a total of 8 temperatures as data. However, one is
missing, so you only have 7. Since the average is known, we start from there:
By adding all the known data, the total is 37. Taking into
account the unknown, the sum is (37 + x). Thus,
(37 + x)/8 = 1.25
This results to x = -27. The low temperature on December 17
was -27.
