Infinite! You can, for example, add -1 and 1 to the equation and make it equal. In x=5, you can have x=5+1-1. and it'd still be the same. To add on to it, you could do x+1-1=5+1-1, etc..
        
             
        
        
        
Answer:
3 seconds.
Step-by-step explanation:
Since we are figuring out when the water balloon will hit the ground, y will need to be equal to 0.
0 = - 16t² - 16t + 96
Now we simply factor the trinomial to find t.
0 = -16(t² - t - 6)
0 = (t - 3)(t + 2)
t - 3 = 0 ⇒ t = 3
t + 2 = 0 ⇒ t = -2
Since we are referring to time, we need to use the positive value. Therefore, the water balloon will take 3 seconds to hit the ground.

Check the picture below.
bear in mind that since we have a radical in the denominator, we'd 
rationalize the denominator to take it off the denominator.
 
        
        
        
Answer:
She will walk and run 148.2 miles in a year
Step-by-step explanation:
She walks: 0.75+0.5=1.25 miles each week 
 And: 1.25 *52=65 miles a year 
She runs : 1.6 miles a week
 And: 1.6*52 =83.2 miles a year
Total miles : 83.2+65=148.2 miles
