Answer:
0.8
Step-by-step explanation:
3(5x+2)+10=4
=15x+6+10=4
After this step you subtract 6 from each side and then subtract 10 from each side and then after that you divide 15x on each side which will give you 0.8.
 
        
             
        
        
        
Step-by-step explanation:
Given 
mass (m) = 5000 kg
velocity (v) = 100 km/h = 100* 1000/ 3600 = 27.78m/s
Now
Kinetic energy 
= 1/2 mv²
= 1/2 * 5000 * 27.78²
= 1929321 joule 
 
        
             
        
        
        
Isolate the w
w/3 = 5
Note the equal sign. What you do to one side, you do to the other.
Multiply 3 to both sides
w/3(3) = 5(3)
w = 5(3)
Multiply
w = 15
15 is your answer for w
hope this helps
