Best ResponseYou've already chosen the best response.2For Nathaniel, he needs 75 min to finish the job. That is in 1 minute, he finishes 1/75 part of the job, right? Same as Brenda with 1/25 so that in 1 minute, both them will finish \(\dfrac{1}{75}+\dfrac{1}{25}= \dfrac{4}{75}\) part of the job. Summary: 1min4/75 ? min75/75??

Best ResponseYou've already chosen the best response.1`Nathaniel can weld a railing in 75 minutes. Brenda can weld a railing 25 minutes faster.` That means Brenda can finish the work in `50` minutes right ?

Best ResponseYou've already chosen the best response.1so we must be solving \[\dfrac{1}{75}+\dfrac{1}{50} = \dfrac{1}{x}\]
