Answer:
A
Step-by-step explanation:
We can break down what each term represents in the equation
60 is the constant. This is the base price that is paid regardless of workers and hours needed
Then there is 12nh. 12 represents the cost per hour for one worker. If the job takes only one hour, then it is 12 dollars per worker. Similarly, if the job only takes one person, then it is 12 dollars for each hour.
The most accurate answer is A
Answer:
(5x^12)/(-2y^8)
-((5x^12)/(2y^8))
Step-by-step explication:
Move the negative sign by multiplying both the numerator and denominator by -1
(5x^12)/(-2y^8)
Move the negative sigh out of the fraction by factoring out -1
-((5x^12)/(2y^8))
distance = speed × time
The distance traveled downwind is 14x. The speed upwind is 4 mph less than 14 mph, so is 10 mph. The distance traveled in x hours upwind is 10x. That distance is 6 miles short of the downwind distance, so we can write the equation ...
... 10x = 14x -6
... 0 = 4x -6 . . . . . subtract 10x
... 0 = x -1.5 . . . . . divide by 4
... 1.5 = x . . . . . . . the downwind travel time is 1.5 hours.
The remaining distance upwind is 6 miles, and it is covered at 10 mph, so will take ...
... (6 mi)/(10 mi/h) = 0.6 h
Then the total trip takes x hours downwind plus x hours upwind plus 6/10 hours to finish the upwind trip:
... 2x+0.6 = 2(1.5) +0.6 = 3.6 . . . hours
