Answer:
it is C. y=3/x
Step-by-step explanation:
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.
If you want the answer youse a calculator or do 21 divided by 38
Answer:
No, because using the distributive property, you would get 5b+15 and 3b+15. The number of b you have is different.
