Answer:
7.425 laps.
Step-by-step explanation:
That would be 378.925 - 371.5
= 7.425 laps,
I believe that the answer would be 45
Steps to solve:
3(5x - 8) = 6x + 39
~Distribute left side
15x - 24 = 6x + 39
~Add 24 to both sides
15x = 6x + 63
~Subtract 6x to both sides
9x = 63
~Divide 9 to both sides
x = 7
Best of Luck!
