Answer:
28 minutes spent in washing the dishes.
Step-by-step explanation:
Given the table
Chore time in minutes
Sweeping 42
Dishes ?
Amanda spent a total of 70 minutes competing her chores this week
Total of 70 minutes spent
42 minutes spent in sweeping . to find the number of minutes Amanda spent in washing the dishes , subtract 42 minutes from the total time spent
let x be the number of minutes spent washing the dishes
![42+x=70](https://tex.z-dn.net/?f=42%2Bx%3D70)
To solve for x , subtract 42 from both sides
![42+x=70\\x= 70-42\\x=28](https://tex.z-dn.net/?f=42%2Bx%3D70%5C%5Cx%3D%2070-42%5C%5Cx%3D28)
28 minutes spent in washing the dishes.
