Answer:
Only n if 2n is/3 when 2nis divide by 3
Reason 1. Given
Reason 2. Definition of Equilateral Triangle
Reason 3. Given
Reason 4. Given
Reason 5. SAS Triangle Congruence
---------
Anywhere you see "given", it's basically just restating what was given in the instructions. Recall that equilateral triangles have all three sides the same length, so that's how we're able to say PK = PL in step 2. The SAS refers to side angle side.
To solve problems like this you can either graph or solve mathematically. To do the ladder we need to solve for one variable at a time. So lets cancel one variable out.
Multiply equation 1 by 2
This will give 4x-2y=14
Now we can get rid of y by subtracting 2 from 1
This will give x=9
Plug back in to either equation, i will use equation 2
3(9)-2y=5 simplify
-2y=-22 solve
Y=11
R+O+P+G+W = 20
a. 5/20 = 1/4
b. 6/20 = 3/10
c. 2/20 + 3/20 = 5/20 = 1/4
