Answer:
x = 3
Step-by-step explanation:
I will assume you meant 5 - (2/3)x = 3. This simplifies to -(2/3)x = -2, or
(1/3)x = 1, so that x = 3.
2
"2/3x" could be interpreted as --------- which would give us a very different
3x result. Use parentheses to
lessen the chances of
misinterpretation.

Answer:
Step-by-step explanation:
Let be "x" the original volume of the solution (in milliliters) before the acid was added and "y" the volume of the solution (in milliliters) after the addition of the acid.
Set up a system of equations:
Applying the Substitution Method, you can substitute the second equation into the first equation and then solve for "x":
The yearly cost would be $138,000.
We will assume that this sample is typical of the shelter's usual numbers. We set up a proportion to estimate how many dogs yearly will have heart worm:
4/50 = x/5750
Cross multiply:
50*x = 4*5750
50x = 23000
Divide both sides by 50:
50x/50 = 23000/50
x = 460
We would expect 460 dogs per year to have heart worm. Multiplying this by the cost for each dog to be treated, we have
460*300 = 138,000.
