Get rid of parenthesis, this is addition it doesn't matter how you add it will give you the same answer
3/8+2/3+1/3
3/8+3/3
3/8+1
3/8+8/8
11/8→1 3/8→1.375
        
             
        
        
        
For part A. 0.85 
For part b. 11.9
Explain
Cost of each track in album A= total cost downloading album a/ total number of track
The problem give us a has 11 trackers and the total cost of download is 9.35 pounds 
9.35/11 
= 0.85 
Now we are given each track cost in album b cost the same as track on A 
Cost of each track in album B is 0.85 
Now we are given if Jane download album B , B will be 14 tracks 
Total cost of downloading is album B= number of tracks in album Bx cost of each track in album B 
14x0.85 pound 
= 11.9 
        
             
        
        
        
d because 24 dived into 1 956 is 82.5
 
        
             
        
        
        
Answer:
The answer to your question is: 20°
Step-by-step explanation:
Data
m∠XZY = 40
m∠XZB = 20
Process
1.- Find the measure of ∠ XAB
    ∠XAB = 40°   because AB ║ YZ
2.- Find the measure of ∠ZAB
      ∠ZAB + ∠XAB = 180
     ∠ZAB = 180 - ∠XAB
     ∠ZAB = 180 - 40
     ∠ZAB = 140°
3.- Find the measure of ∠ABZ
     The sum of the internal angles in a triangle equals 180°
      ∠AZB + ∠ZAB + ∠ABZ = 180
      20° + 140° + ∠ABZ = 180
      ∠ABZ = 180 - 20 - 140
     ∠ABZ = 20°
