Answer:
- 0.5 - 1.7 = - 2.2
Step-by-step explanation:
We need to add two numbers using the number line.
Steps to Add Numbers on the Number Line:

We are adding two negative numbers. Locate the first number which is -0.5. Then, add negative 1.7 to it which means moving the existing point 1.7 units to the left of the number line.
So, we get 2.2 on the left.
2.2 is left side it means sign is negative.

Answer:
39
Step-by-step explanation:
The chords are equal to eachother. First multiply their divided lengths together:
9(3x-9)=21(x+1)
27x-81=21x+21
x=17
CD= 21+x+1
21+17+1=39
CD= 39
