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.
1. 5(n+4)
2. 5h+30
3. 75/h
4. seven more than twice a number
5. six times the sum of a number and nine

Answer:
+12,008,304
Step-by-step explanation:
Your calculator can tell you the product is positive. (Any product involving an even number of minus signs will be positive.)
(-38)(378)(-836) = (38)(378)(836) = 12,008,304 . . . a positive answer
