Answer:
4200
Step-by-step explanation:
Time taken by Lester 30 seconds
Time taken by Ralph = 35 seconds
Their rate :
Lester = 1/time taken = 1/30
Ralph = 1/ time taken = 1/35
Combined rate:
1/30 + 1/35 = (35 + 30) / 1050 = 65 / 1050 = 0.0619047 per boot
Time taken = number of boots / combined rate per boot
Time taken = 260 / 0.0619047
Time taken = 4200 seconds
Answer:
m= rise of the bank balance over/the increase of time y= is your bank balance x=is the time in weeks b= is your y-intercept when x=0
Step-by-step explanation:
To write the equation use y-intercept formula which is y=mx+b
Step 1: Prioblem
