Answer:
7
Step-by-step explanation:
1) for '8'; '3'; and '10':
8/2+3+3=10
2) for '2'; '5' and '11':
2/1+5+5=11
3) for '6'; '2' and '?':
6/2+2+2=7
Yes, because the afternoon rate is just the morning rate split in half. Instead of checking the temperature every hour and a half, the temperature was checked every 45 minutes. And, the temperature rate was also split in half when the time was split in half. So basically, if the 2 degrees every 45 minutes was multiplied by 2,(both the time and the temperature) or if the 4 degrees every 90 minutes was divided by 2, (once again, both the time and the temperature) then, they would both be either 2 degrees every 45 minutes, or they would both be 4 degrees every 90 minutes.
To find the length of the yellow segment, we have to use Pythagorean's Theorem. But first, we have to find the length of the black line at the bottom.
Where a = 4ft and b = 9ft.
So, the length of the black segment is 9.8 feet.
Now, we find the yellow line length
Where a = 4 and b = 6.
<h2>Therefore, the length of the yellow line is 7.2 feet.</h2>

Step-by-step explanation:
Answer:
These steps show you the way:
Write the system as a matrix equation.
Create the inverse of the coefficient matrix out of the matrix equation.
Multiply the inverse of the coefficient matrix in the front on both sides of the equation.
Cancel the matrix on the left and multiply the matrices on the right.
Multiply the scalar to solve the system.
You finish with the x and y values.
