Answer:
   $128.49
Step-by-step explanation:
4 gallons at $15.72 each is 4×$15.72 = $62.88
3 gallons at $21.87 each is 3×$21.87 = $65.61
The total purchase is ...
 $62.88 +65.61 = $128.49
Tim will be spending $128.49 on paint.
 
        
                    
             
        
        
        
Answer: 180 tickets for $40
Step-by-step explanation:
     To answer this question, we need to find a pattern;
15 / 3 = 5
60 / 15 = 4
-> If you divide, we find a pattern of the quotient with 5... 4... so we can assume the next is 3
     Using this pattern;
60 * 3 = 180 tickets for $40
 
        
             
        
        
        
The answers for the exercise shown above are the second option, the third option, the fifth option and the sixth option, which are:
 2) <span>Distribute 2 to 9.7 and −4.8x.
 3) Combine 3.4 and 19.4.
 5) Substract 22.8 from both sides.
 6) Divide both sides by −9.6
 The steps are shown below:
 </span><span>3.4+2(9.7-4.8x)=61.2</span> 
 3.4+19.4-9.6x=61.2
 22.8-9.6x=61.2
 228-22.8-9.6x=61.2-22.8
 -9.6x=38.4
 -9.6x/-9.6=38.4/-9.6
 x=-4
        
                    
             
        
        
        
For Sammie the equation would be S=3N.
If Nora (N) has 4 goldfish, you substitute N=4 into the previous equation to find out how many goldfish Sammie has.
>  S= 3 x 4 
= 12
The next part of the question is asking you how many goldfish do Sammie and Nora have in all. If Sammie has 12 goldfish and Nora has 4 goldfish, the equation would be 12 + 4= 16
The answer would be 16 goldfish in total.
