Step-by-step explanation:
so the ratio of the recipe is 32/48 of pineapple juice and orange juice.
that can be simplified to the ratio of 2/3.
now, she has only 20 floz of pineapple juice. 
20/x = 2/3
60/x = 2
60 = 2x
x = 60/2 = 30
she needs 30 floz of orange juice with the 20 floz of pineapple juice to maintain the prescribed ratio for fruit punch.
 
        
                    
             
        
        
        
Formula used: 40+x = 4x-3     x is used for <em>ET</em>
Step-by-step explanation:
40+x = 4x-3
<u>+</u><u>3</u> <u>+</u><u>3</u>
43+x = 4x
 <u>-</u><u>x</u> <u>-</u><u>x</u>
<u>43</u> = <u>3x</u>
 3 3
14.3 = x
then substitude this on 5x+3 on <em>W</em><em>T</em> and you arr good
