You would add 10.3 and 5.9 which would equal 16.2, and subtract that from 20 and change that decimal into a fraction, which would be 19/50
Answer:

Step-by-step explanation:
We have the equation 
In order to solve for x, we need to get all of the x's to one side and everything else to the opposite side

First, we can add 1 to each side

Now, we can add x to each side

Next, we can divide each side by 2

And here is our answer.
Answer:
5t-4n+2
Step-by-step explanation:
n-5n=-4n
5t-4n+2
The area is 24² because 8*3 is 24
The perimeter is 8+8+3+3 which is 16+6 and that equals 22
22 is the Perimeter and the Area is 24²
Answer:
Step-by-step explanation:
Area of a Semi Circle
Area = 1/2 pi r^2
r = d/2
r = 3/2
r = 1.5
Area = 1/2 3.14 * 1.5^2
Area = 1/2 * 3.14 * 2.25
Area = 3.5325
Area of Rectangle
L = 12 Yd
W = 4 Yd
Area = L * W
Area = 12 * 4<u> = 48 </u>
Total Area = 51.5325
