Answer:
$0.25
Step-by-step explanation:
You can use systems of equations to solve this.
3a+2p = 1.25
5a+p = 1.5
Multiply the second equation by 2.
3a+2p = 1.25
10a+2p = 3
Subtract the bottom from the top
-7a= -1.75
Divide by -7
a= 0.25
Each apple is $0.25 (in this case, the peach also costs $0.25)
 
        
             
        
        
        
Step-by-step explanation:
EXAMPLE OF SURFACE AREA
1/2 × (30×4) × 39 + (30×30)
= 60 × 39 + 900
= 2340 + 900
= 3240 
 
        
             
        
        
        
24x^2 +25x - 47                     53
----------------------- = -8x -3 - ---------------
ax-2                                     ax-2
add 53/ax-2 to each side
24x^2 +25x - 47+53                     
-----------------------         = -8x -3 
ax-2                                     
24x^2 +25x +6                   
-----------------------         = -8x -3 
ax-2       
multiply each side by ax-2
24x^2 +25x +6   = (ax-2) (-8x-3)
multiply out the right hand side
24x^2 +25x +6  = -8ax^2 +16x-3ax +6
24 = -8a      25 = 16 -3a
a = -3          9 = -3a
                    a = -3
