X=44°
you write 2x-6=82, subtract 6 on both sides so ur left with 2x=88, you divide both sides by 2 and you get 44
That is the Distributive property of equality
The another way to state the transformation would be 
<u>Solution:</u>
Rotation about the origin at 
: 
The term R0 means that the rotation is about the origin point. Therefore, (R0,180) means that we are rotating the figure to about the origin.
So, the transformation of the general point (x,y) would be (-x,-y) when it is rotated about the origin by an angle of .
Hence according to the representation, the expression would be 
.
Alright, denote sweatshirts by x and tshirts by y:
for billy: 2x+3y=35$
for jordan:3x+3y=45$
We need to get rid of one of the unknowns inorder to solve, therefore we will subtract the two equations from each other. This will get rid of the y variable(3y-3y=0)
2x+3y=35$
-
3x+3y=45$
=
-1x=-10$
we get rid of the negative, which leaves us with x=10$. Knowing this info, we can now easily calculate y:
2x+3y=35$
2(10)+3y=35$
20+3y=35$
3y=15
y=15/3
y=5
Hope this helps!
