Answer:
y=-3/4x+5.5
Step-by-step explanation:
 
        
             
        
        
        
So we need to solve:

First is important to note that both terms on the left side of the equation have a common factor because they are both divided by y. Then:

Then:

So the solution is y=6. Then option A is correct and you need to write the 6 between the symbols { }.

Answer:
7.$95 8. $112.50
Step-by-step explanation:
7.
50 divided by 100 is 0.5, then times by 90 is 45.
45 plus 50 is 95.
8.
$150/4=$37.50
$150-$37.50=$112.50
