- Definition of a Line: A line is 180°
Step-by-step explanation:
<u>Step 1: Set up Equation</u>
m∠BDC + m∠CDA = 180°
(-7x + 12)° + (-8x + 48)° = 180°
<u>Step 2: Solve for x
</u>
- Combine like terms: -15x + 60 = 180
- Isolate x term: -15x = 120
- Isolate x: x = -8
<u>Step 3: Find m∠BDC
</u>
- Define: m∠BDC = (-7x + 12)°
- Substitute in x: m∠BDC = (-7(-8) + 12)°
- Multiply: m∠BDC = (56 + 12)°
- Add: m∠BDC = 68°
Given:
A segment has endpoints V and X.
To find:
The two names for the segment.
Solution:
A line segment is a small part of a line and it has two end points. The name of a segment is described by its end points.
For example: If A and B are two and points of a line segment, then the names for the segment are 
and 
.
It is given that the segment has endpoints V and X.
Therefore, the two names for the segment are 
and 
.

Answer:
C
Step-by-step explanation:
Take the first number from the money earned number list. Then, divide it by the first number from the other side. This way you will find the rate of change. Do that to every answer choice, and compare the rate of changes to find the greater one.
Answer:
21/2
Step-by-step explanation:
(x-8)/5=2/4
step 1 you simplify if you can to make it easier
(x-8)/5=1/2
step 2 multiply each side by 5
x-8=5/2
step 3 add each side by 8
x=5/2+8
16/2+5/2=21/2
x=21/2
