Answer:
b = 5
Step-by-step explanation:
All quadratic equations are formed in the format of
+ bx + c = 0
Using this formula, we can re-arrange the equation to fit the given format.
- 2 = -5x
+ 5x - 2 = 0
5 is plugged in for "b" in this equation, therefore b = 5.
Leslie:
h= hours
3/4h=4 1/2 laps
divide both sides by 3/4 or .75
1 hour = 6 laps
Kayla:
3/4h= 3 1/2 laps
divide both sides by 3/4
1 hour = 4 2/3 laps
Leslie can do C
1_ 1/3 more laps in an hour than Kayla
