Solve the equation for x
25-3x=40

X=-5

explanation:
you have to do inverse operation, so subtract 25 and -25 and then on the other side you do 40-25, which equals 15. After that you get -3x=15 and divide -3 on both sides.

The answer will be -5
What ever you do to one side you do to the other

First subtract 25 from itself and do the same to the total
25-3x=40 -3x=15

Next divide -3 from itself and the total ( keep in mind that when you multiply or divide a negative by a positive the answer will be a negative)
-3x=15 X=-5

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.

Are you trying to figure out the volume?
