Elias and niko are polishing the silver at the heritage museum. elias could polish all the silver himself in 40 minutes. that task would take niko 50 minutes to complete alone. which table is filled in correctly and could be used to determine how long it would take if elias and niko polished the silver together?

We let x be the number of hours both could the job together.

The fraction of the job done by Elias is

x/40

The fraction of the job done by Niko is

x/50

Together they would be able to finish the job

x/40 + x50 = 1

x = 1 / (1/40 + 1/50)

x = 22.22 min

Step-by-step explanation:

should be the first table

Step-by-step explanation:

351.23

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
