katie has crazy tendancy that slows her down - she takes one step backward for every two she takes forward. How many steps will it take susan to get from the bedroom to the kitchen, which is twenty paces?

2) let x characterize the sum of his youngster's a at the same time as now let y characterize Jack's age now In 20 years Jack's age is y + 20, and the sum of his youngster's a at the same time as will be x + 20 + 20 + 20 = x + 60 x = y x + 60 = 5/3(y + 20) x + 60 = 5/3(y + 20) y + 60 = 5/3y + 100/3 y + 60 = a million/3(5y + 100) 3(y + 60) = 5y + 100 3y + 100 and eighty = 5y + 100 100 and eighty = 5y - 3y + 100 100 and eighty - 100 = 2y 80 = 2y 80/2 = y 40 = y Jack is 40 years previous now

Assuming a pace = a step, then the answer is 20.

56 steps
she only did the first step and last step 1 time
the other 18 steps, she actually stepped on 3 times
so 18 x 3 = 54
54 + 1 + 1 = 56

60 steps (forward and backward) to go 20 forward
2 forward, 1 backward = 1 forward (3 steps total)
2 forward, 1 backward = 2 forward (6 steps total)
etc.
