The answer is 24. think of x as the original amount, and y as the new
amount. y times 1.5 is x, and y+12 is x. reverse that to figure out y,
which is what we need, and you have x/1.5 = y as well as x-12 = y. Use
the equal values method and make an equation x/1.5=x-12. solve this
equation to get x, which is 36. to figure out the new amount, y, you
need to subtract 12, which would help you get 24 as your final answer.
Answer:
Step-by-step explanation:
P=2a+b
Solve for a.
Divide both sides by 2 to isolate a.
P=2a+b
P/2=a+b/2
When you rewrite the equation, it becomes:
a=P/2-b/2 (The sign changes from a positive to a negative because you need to move P/2 to the other side to get a to one side)
Therefore, your final answer is: a=P/2-b/2
Hope this helped!

The graph has a y intercept of positive 2
Answer:
x = 200
Step-by-step explanation:
Plug in 15 as y into the equation and solve for x:
1/5x - 2/3y = 30
1/5x - 2/3(15) = 30
1/5x - 10 = 30
1/5x = 40
x = 200
So, when y = 15, x = 200
