 Answer:
x = -30
Step-by-step explanation:
subtract 7 from both sides ( 7+2/5x -7, -5-7 )
simplify ( 2/5x = 12 )
multiply both sides by 5 ( 2/5x times 5 = 5 (-12) )
simplify ( 2x = -60 )
divide both sides by 2 ( 2x / 2, -60 / 2 )
x = -30
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Given: 
Initial speed (Vi) = 30 mi/h = 67.1 m/s
Final speed (Vf) = 52 mi/h  = 116.32
Time period(t) = 5 seconds
We know the formula of acceleration in terms of initial speed, final speed and time:
