Roland and sam wash dogs to make extra money rollin can wash all the dogs in 4 hours sam can wash all the dogs in 3 hours how long will it take them to wash all the dogs if they work together

Step-by-step explanation:

Given,

Rollin can wash all the dogs in 4 hours,

The work done by Rollin in one day =

Also, Sam can wash all the dogs in 3 hours,

The work done by Sam in one day =

The total work done by both Rollin and Sam in one day =

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
