<span>2x + 4y = 36 
3x - 4y = -6
--------------add
5x = 30 
  x = 6
</span>2x+4y=36 
2(6)+4y=36 
12 + 4y = 36
4y = 24
  y = 6
answer
<span>(6, 6) is a solution of equations
</span><span>(4,7) is NOT a solution of equations</span>
        
                    
             
        
        
        
Two inequalities are equivalent if they have the same set of solutions.
x - 5 ≤ 6 - 5
x - 5 ≤ 1    |add 5 to both sides
x ≤ 6
 
        
             
        
        
        
Answer:
372,000 femtoseconds
Step-by-step explanation:
<u>1 picoseconds = 1000 femtoseconds</u>
372 picoseconds = 1000 * 372 femtoseconds
1000 * 372
372,000
Answer:  372,000 femtoseconds
 
        
             
        
        
        
Answer:
a testable proposition that explains an observed phenomenon or answers a question
Step-by-step explanation:
Basically an hypothesis is a theory given as a solution to a question proposed by a problem in from of you, but that it needs testing before it can be taken as truth or not
