Answer 1

28 minutes spent in washing the dishes.

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`

To solve for x , subtract 42 from both sides

`42+x=70\\x= 70-42\\x=28`

28 minutes spent in washing the dishes.
