Answer: 
Step-by-step explanation:
Given
The temperature on Monday was 
By Tuesday, it becomes 
Change in temperature is the difference between the two temperatures.

Therefore, the change in temperature is
.
The formula for surface area of a sphere: A = 4 pi r^2.
Since the radius is 30 m then A = 4pi30^2.
30^2 x 4 =3600
A=3600pi m
T,A,Y are 40 and 2T,X,B,Z are 80
Plug 4 for x and solve.
y = -3/4 * 4 + 3
y = -12/4 + 3
y = -3 + 3
y = 0
So the missing coordinate is 0.
The answer for " J " would be 228
