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
[tex]42+x=70[/tex]
To solve for x , subtract 42 from both sides
[tex]42+x=70\\x= 70-42\\x=28[/tex]
28 minutes spent in washing the dishes.
