Answer:
A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours.Express the total distance traveled in terms of x.
Total distance covered by the man in terms of 'x' = (12.5x-285)miles
Step-by-step explanation:
Given:
Speed of a man = 'x' miles/hour
Time taken =
hour
So, distance = product of speed and time.
Distance covered in term of 'x' 
Now,
Speed =
miles/hour
Time taken=
hours
Distance
= 
= 
=
miles
Total distance covered by the man = Summation of
and 
= 
=
miles
So the total distance covered by the man in terms of 'x' = (12.5x-285) miles.
Answer:
6 teaspoons
Step-by-step explanation:
2 teaspoons = 1/3 tsp of salt
6 teaspoons = 1 tsp of salt
This was done by multiplying 2 by 3 since 3 thirds (3/3) make one whole.
So if 2 teaspoons are used for 1/3 teaspoon of salt, 4 teaspoons would be used for 2/3 teaspoon of salt and 6 teaspoons would be used for 1 teaspoon of salt.
27 away. (7, - 6) is in quadrant 2 and (-9,5) is in quadrant 4. 16 (-9 + 16 = 7) + 11 (-6 + 11 = 5) = 27
