Answer:
25.5 mph
Step-by-step explanation:
So Bradley's speed can be modeled by the equation y=2x+40 where y=speed, x=time in hours after noon, and b=initial speed
So 12:15 is 15 minutes after noon, which is also 0.25 or 1/4 of an hour after noon. This is the x-value. Plug this into the equation to get his speed at 12:15
y=2(0.25)+40
y=0.5+40
y=40.5
So his speed was 40.5 at the time and since he was going 15 miles over the speed limit, the speed limit is 15 less than his speed
40.5 - 15 = 25.5
The answer is C. 3.11 because if you divide 15.55 divided by 5 you will get 3.11
Answer: 2(N+15) = 6N
======
We let N be the number.
Then, "<span>the sum of a number and fifteen" would be
N + 15
Two times this sum would give us
2(N+15) ... you must distribute!
This must be equal to six times the number. Six times the number is 6N, therefore
2(N+15) = 6N</span>
