6.4 - 2x - 6.63x = 610.5
subtract 6.4 from both sides
-2x -6.63x =604.1
collect like terms
-8.63x = 604.1
divide both sides by -8.63
x= -70
I did this to get 47.5 as the answer not 47 im not sure why but i did (61-7+7×1/2)+17 using the PEMDAS please excuse my dear aunt sally

Answer: Associative property
Step-by-step explanation:
Answer:
Factoring the trinomial:
we get the factors 
Step-by-step explanation:
We need to factor the trinomial: 
We can factor the trinomial by breaking the middle term i.e 13x
Such that adding or subtracting gets the both terms we get 13x and multiplying both terms we get 12x^2
We can break 13x as: 12x and x
Adding them we get 13x and multiplying them we get 12x^2
So,

So, Factoring the trinomial:
we get the factors 
Answer:
y = 70 degrees
x = 11
Step-by-step explanation:
The side opposite x + 2 is equivalent so they will both be equal to 13.
To get the meaning of x, simply subtract 2 from 13 giving you x = 11.
Y is across from corner C, which is 70 degrees. These angles are equivalent to each other, meaning that angle y is also 70 degrees.
Hope this helps you :)
