Answer:
0.2 hours
Step-by-step explanation:
The depth, d of snow (in cm) that accumulates in Harper's yard during the first h hours of a snowstorm can be calculated using the equation:
d=5h
When d=1cm, we want to determine the value of h.
1=5h
h=1/5=0.2
Therefore, it takes 0.2 hours for 1 centimeter of snow to accumulate in Harper's yard.
Answer:

Answer:
20x^2 - 107x - 10.
Step-by-step explanation:
8x - 108x - 10 - (9x^2 + 7x -29x^2)
simplifying:
-100x - 10 - (7x - 20x^2)
20x^2-100x - 7x - 10
20x^2 - 107x - 10
