Answer:
1. AB=CB def of isosceles triangle
2. AD=CD DEF of median
3. BD=DB reflexive property
4. ADB=CDB SSS
Step-by-step explanation:
ummmm its just the right answer trust
30 + 2w = 2 • (w - 15)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation
Solve : w-15 = 0
Add 15 to both sides of the equation :
w = 15
Zero Property of Multiplication hope this helps
Solution: Alyssa is incorrect.
In fact 
.
If we cross-multiply the above equation, we have:
Therefore, they are equal.
Also, if we reduce the given fractions, we have:
And
Since both the fractions reduced to 
, therefore fractions are equivalent.
I'm pretty sure its 127.8
