Lester and Ralph work at an athletic shoe store in the mall, but whenever they goof off too much, their boss punishes them by making them lace-up all the inventory. I f it takes Lester 30 seconds to lace up a high top and Ralph 35 seconds to do the same, how many seconds will it take them to lace-up 260 high tops?

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

p> q if you calculate p is100 q is 79

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
