Answer:
13.3 hours
Step-by-step explanation:
% done by Nancy in 8 hours = 100% = 1
8 (% done by Nancy in 1 hour) = 1
% done by Nancy in 1 hour = 1/8
n = 1/8
Similarly,
% done by Nancy in 5 hours + % done by Carole in 5 hours = 1
5 (% done by Nancy in 1 hour + % done by Carole in 1 hour) = 1
n + c = 1/5
Since n = 1/8
% done by Carole in 1 hour = 3/40
Thus,
time taken by Carole to finish the job
Hey!
Hope this helps...

This really depends on what the question asks, because if you substitute 0 for x, the equation comes to 0 > 0 (which is a logical error), if you substitute 1 for x, the equation comes to 0 > -5 (which is the correct answer). If you substitute -28 for x, you get 0 > 28 (and we know 28 will always be greater than 0, but 0 will never be greater than any positive number), this is the same if you were to substitute -36 for x, you get 0 > 36
So the correct answer is D.) x > 1
because you get 0 > -5 (when you plug in 1 for x), and 0 will always be greater than any given negative number...

One more thing, this question is asking you to MAKE IT TRUE, IF it said 0 ≥ -3x - 2x... THAN A, B, and C would be correct, OR IF it said 0 ≤ -3x - 2x... THAN B and D would be correct, BUT because it only says 0 > -3x - 2x... THAN ONLY D is correct...
With a simple change of signs, you can dramatically change the answer to this equation

Answer: y = 24.95 + 5x
Step-by-step explanation: Since you would have an original price of 24.95 then that would be your basically "start off" number and since you have 5 cents per mile then you would have to have a variable for that in order to be correct
