No . . . while the difference represents the absolute magnitude between two numbers . . . for example . . .
<em>The difference between 5 and 2 is . . . 3</em>
<em>The difference between 6.4 and 9.5 is . . . 3.1</em>
 . . . there is still the chance that the difference may be zero . . . in which case the difference is neither positive nor negative
. . . so in short . . . the answer is . . . <u><em>NO</em></u>
        
             
        
        
        
Answer:
cost of paint set = $ 13.64 
cost of sketch book = $ 6.82 
cost of brush = $ 4.55 
Step-by-step explanation:
Let the cost of paint set is s. 
cost of sketch book = s/2 
cost of brush = s/3
Money spent = $ 28 - $ 3 = $ 25 
So, 
s +  s/2 + s/3 = 25
6 s + 3 s + 2 s = 150 
11 s = 150 
s = $ 13.64
cost of paint set = $ 13.64 
cost of sketch book = $ 6.82 
cost of brush = $ 4.55

 Step-by-step explanation:
Remember, math is a language
when you see per think fractions
15.2 miles per hour = 15.2 miles / 1 hour
since this is a fraction, Units can cancel just like numbers
To cancel miles and be left with hours rearrange the fraction 
1 hour / 15.2 miles
then multiply by 72 miles

the miles cancel and youre left with hours! 
so youd write and solve 72 / 15.2
