Answer:
x = -8
Step-by-step explanation:
1)  5x + 7= 7x +23
Move the terms
2)  5x + 7 -7x = 23
Collect like terms
3)  5x -7x = 23 - 7
Calculate
4)  -2x = 16
Divide both sides by <em>-2</em>
5)  x = -8
 
        
             
        
        
        
-1/2 is bigger than -8/15

It is given in the question that 
A projectile is fired at 657 mi/hr. how fast is that in meters per second? use the conversion factor 1 mile = 1610 m. 
So we need to convert miles per hour to meters per second.
And it is given that 1 mile  equals to 1610 meters and 1 hour equal to 3600 seconds.
So we will get
