Answer:
Erik's average speed exceeds the speed limit by 6.91 miles per hour.
Step-by-step explanation:
Let suppose that Erik travels at constant speed. Hence, the speed (
), measured in miles per hour, is determined by following equation of motion:
(1)
Where:
- Distance, measured in miles.
- Time, measured in hours.
Please notice that a hour equals 60 minutes. If we know that 
and 
, then the speed of Erik is:
Which is 6.91 miles per hour above the speed limit.
He would make $117 because 7x15=105 and 1.50x8=$12.00 add that together you get 117
Answer:
infinite 7v + 6v could be anything theres no context to find out what v represents and how much it could amount to
Step-by-step explanation:
Answer:
Step-by-step explanation:
49b² - 81 = (7b)² - 9 ²
by identity : 49b² - 81 = (7b - 9)( 7b + 9)
3+8x-2y-x+1+4y
Combine all like terms and
7x+4+2y is your answer
