Answer:
   x = 2.5 or 7.5
Step-by-step explanation:
Subtract 3/4.
   |5 -x| = 10/4 = 2.5
This resolves to two equations:
- 5 -x = 2.5   ⇒   x = 5 -2.5 = 2.5
- 5 -x = -2.5   ⇒   x = 5 +2.5 = 7.5
The solutions are x = 2.5 or 7.5.
 
        
             
        
        
        
12/3 = 4
4 cars per hour
4 x 5 = $20
20 x 8 = $160 for 8 hrs
        
                    
             
        
        
        
Answer:
The correct answer AC = 11.52
Step-by-step explanation:
From the figure attached with this answer shows the triangle ABC.
BC=4 centimeters, m angle B=m angle c, and m angle a = 20 degrees
To find AC
From the figure we can see that D is the mid point and AD⊥BC
Then BD = CD = 4/2 = 2 cm
<BAD = 10° and <CAD = 10°
By using trigonometric ratio,
sin 10 = CD/AC = 2/AC
AC = 2/sin 10 = 2/0.1736 = 11.52
Therefore the value of AC = 11.52 cm
 
        
                    
             
        
        
        
Is it 22.5 b/c 22.5 *2 = 45 and 22.5 +22.5= 45. or do u mean both numbers have to be the same
