12.6 × 0.25 = 3.15
i hope this helps
Initial velocity of John's car (V1) = 0 miles per hour
Final velocity of John's car (V2) = 45 miles per hour
Time taken for acceleration = 45 seconds
Then
Acceleration = (V2 - V1)/Time taken
= (45 - 0)/15 miles per hour per second
= 45/15 miles per hour per second
= 3 miles per hour per second.
So the approximate rate of change in the miles per hour that John's car accelerated is 3 miles per hour per second. The correct option among all the options given in the question is option "A".
Step-by-step explanation:
give some hint
but I think the answer should be 8
For the -5+5y=40 the answers is y=9
And for 4x+3y=24 is x=-3/4y +6
