A. x = -6
6-x-x = 18
6-2x =18
-2x = 12
x = -6
It's 5/2 not simplified and 2.5 simplified
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

To solve for x , subtract 42 from both sides

28 minutes spent in washing the dishes.
Answer:
Victor should buy Legend because it has a better unit rate
<em></em>
Step-by-step explanation:
See attachment for complete question.
To determine which car has more gas efficiency, we have to calculate the slope of each car.
Vehicle 1: Legend
Take any two corresponding points from the table


The slope is then calculated using;




<em>This implies that this vehicle (legend) travels 18 miles per gallon of gas</em>
Vehicle 2: Supreme
Take any two corresponding points from the graph


The slope is then calculated using;




This implies that this vehicle (supreme) travels 16.7 miles per gallon of gas
<em>Base on the calculations above, Victor should buy Legend because it has a better unit rate</em>
I-1 is the polynomials because I is the linear term and 1 is the constant
