Answer:
The correct answer is
.
Step-by-step explanation:
We want to solve for y in the given equation. We can do this by rearranging the equation and using operational techniques to simplify.







Because we have the <em>y</em>-variable isolated from the rest of the equation, we are done!

All the interior angles of a triangle add up to 180 degrees
Answer:
The value of r=
The value of x=
Step-by-step explanation:
Given that,
A) 
Now,

8(2r-2)=9(7r+10)
16r-16=63r+90
-16-90=63r-16r
-(16+90)=47r
-106=47r
r=
B) 
Now,

5(x+5)=9[3(x-2)-1]
5x+25=9[3x-6-1]
5x+25=9[3x-7]
5x+25=27x-63
25+63=27x+5x
83=32x
x=
