Answer:
x=65
Step-by-step explanation:
x-5=60
Add 5 to both sides 
x=65
 
        
             
        
        
        
Answer: 
Step-by-step explanation:
Given: Mass of baseball=0.145 kg
Speed of baseball=40 meters per second
Also it is given that The kinetic energy (in joules) of a moving object can be calculated from the expression 
 , where 'm' is the mass of the object in kilograms and 'v' is its speed in meters per second.
Thus, the kinetic energy of baseball=

 
        
                    
             
        
        
        
2,852.1 miles / 10 days = about 285.21 miles per day .
        
                    
             
        
        
        
I think the trick is to add the two middle terms together.  (And the 2 end terms).
8 - 12x 
The variable is x. The coefficient is - 12.
8 is a constant.
The coefficient always goes with a variable.
3x^2 + 2x + 5
Nothing can be combined.  The leading coefficient is 3 (which goes with the greatest power of the variable x^2 in this case) and the other coefficient is 2. 5 is a constant.
