We know that
• Lashonda purchased a prepaid phone card for $20.
,
• Long-distance calls cost 8 cents a minute.
,
• The remaining credit on her card is $17.12.
This problem can be expressed as

Where <em>x</em> is the number of minutes. 
We solve the equation for <em>x</em>

Then, we divide by -0.08 the equation

<h2>Therefore, Lashonda's call last 36 minutes.</h2>
 
        
             
        
        
        
Answer:
The result is 150 + 1.5d
Step-by-step explanation:
We want to translate the wordings into algebraic expression.
Firstly, we increase 120 by d%
d% = d/100
So increasing 120 by d % means;
120 + (d/100 * 120)
= 120 + 1.2d
Then increase this by 25%
= (120 + 1.2d) + 25/100(120 + 1.2d)
= 120 + 1.2d + (120+1.2d)/4
= 120 + 1.2d + 30 + 0.3d
= 120 + 30 + 1.2d + 0.3d
= 150 + 1.5d
 
        
             
        
        
        
Answer:
Therefore we can say that 98 boxes will be needed to hold all the paperweights.
Step-by-step explanation:
i) there are 1657 souvenir paperweights that need to be packed in boxes.
ii) each box will hold 17 paperweights
iii) therefore the number of boxes that will be needed are
    =  =
  =  = 97.471
 = 97.471 
iv) Therefore we can say that 98 boxes will be needed to hold all the paperweights.
 
        
             
        
        
        
Answer:
29/18
Step-by-step explanation:
-11/6 + m = -2/9
Add 11/6 to both sides.
+11/6  -11/6 + m = -2/9  +11/6
m=29/18
