Answer:
Step-by-step explanation:
First you need to use the distributive property:
3-2x+2x+3(6-3x)-7(1-2y)=25+6y
3-2x=2x+18-9x-7+14y=25+6y
3-2x=-7x+11+14y=25+6y
Then Split up the equations.
3-2x=-7x+11
Subtract 3 from both sides 
-2x=-7x+8
Then add -7x to both sides
5x=8
Then divide both sides by 5x
X=
To solve for y: just use 14y=25+6y
Subtract both sides by 6y
8y=25
Then divide both sides by 8y
y=
 
        
             
        
        
        
No because that would just be measuring freshman a better sampling method would be surveying the same number of students for each grade
        
             
        
        
        
5n + (-6) = -2
add 6 to -2
5n = -2 + 6
5n = 4
divide both sides by 5
n = 4/5

Answer:
Profit earned by Randi on her last snow shoveling and salting job= $ 60
Let number of hours spent by Randi on that day while working as a shoveler and salter = x hours
Writing the statement in terms of inequality
→ Number of hours worked= Amount of profit earned
→ x=60
→If profit is less than $60.00, then Number of hours will be less.
→If Profit is more i.e greater than $60.00, Number of hours will be more.
