Step-by-step explanation:
total purchase less than $5000 $5000 to $10,000 over $10,000. discount 25% 30% 35%
 
        
                    
             
        
        
        
Set up an equation:
3x - x = 28
Simplify:
2x = 28
Divide both sides by 2
X = 14
3(14) = 42
The numbers are 42 and 14
 
        
             
        
        
        
Answer:
u = 5/4
Step-by-step explanation:
to evaluate for the value of u we would simply open the bracket and then evaluate for the value of u by collecting the like terms together.
solution
3=7(4 - 2u)-6u
3 = 28- 14u - 6u
collect the like terms
3 + 14u + 6u = 28
20u = 28 - 3
20u = 25
divide both sides by the coefficient of u which is 20
20u/20 = 25/20
u = 5/4
 
        
                    
             
        
        
        
Answer:
1. No
2. No
3. Yes
4. No
Step-by-step explanation:
The first one isn't  proportional because it doesn't  start at 0 
The second one isn't proportional because there isn't  a pattern between  the coordinates
The 3rd one is a proportional relationship because it starts at 0 and there is an equal amount of space between each coordinate and there is evidentially a pattern.
Finally, the  4th one isn't proportional because the last coordinate doesn't correspond w/ the others
Plz mark me brainliest if correct :)
