First substitute .5x in for y to get a solvable equation. You should get 6x+8(.5x)=30. Then multiply 8 times .5 to get 6x+4x=30. Then combine like terms (6x+4x) to get 10x=30 and divide both sides by 10 to get x=3. Then plug this x value (3) into the other equation (y=.5x) to find the value of y. Y=.5(3) so y=1.5. Therefore the answer is B.

Answer:
36 degrees for each angle.
Step-by-step explanation:
If you divide 180 by 5 (for each point in the star) you get 36 degrees.
Answer: Triangle B
Step-by-step explanation: Congruent just means which shape matches the others, like as you see D and F are congruent as well as A, C, and E.
Answer: 
Explanation:
We have been given with the equation -3x+1+10x=x+4
We will collect the terms that are written in variable of x in one side and the constant values on the other side we will get
-3x+10x-x=4-1
After simplification we will get 6x=3
which implies x=1/2
When x from right hand side shift will shift to left hand side it will change its sign and similarly when 1 from left hand side shift to right hand side change its sign.
Therefore, x=1/2
