Answer:
The final temperature was 9 degrees.
Step-by-step explanation:
You can first multiply 13x2, 7x2, and 9x2. Then you subtract 26 and 18 from 34. then add 14
 
        
             
        
        
        
This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25
        
             
        
        
        
Answer:
x = 14/3 - (2 y)/3
Step-by-step explanation:
Solve for x:
3 x + 2 y = 14
Subtract 2 y from both sides:
3 x = 14 - 2 y
Divide both sides by 3:
Answer:  x = 14/3 - (2 y)/3
