Answer:
2) x = 6    y = 7      3) x = -5    y= 2
Step-by-step explanation:
2) 10x - 8y = 4
    2(-5x + 3y = -9)
-10x + 6y = -18
  10x - 8y =   4      Add both equations together
          -2y = -14
          y = 7            Divide both sides by -2
10(x) - 8(7) = 4       Plug in 7 for the y to solve for x
10x - 56 = 4  
      + 56 + 56        Add 56 to both sides
10x = 60 
x = 6                      Divide both sides by 10
3) Where the two lines intersect, that is the solution to x and y. 
The lines intersect at (-5,2). x = -5      y = 2 
 
        
             
        
        
        
You have to multiply 36 times 4 =144 . So you do this like this (30 times 4) +(4 times 6)= so (120)+(24)= 144. Answer is 144
 
        
                    
             
        
        
        
You need to get a common denominator. 3/4= 9/12 because 3x4=12 and 3x3=9. you must do the same thing to both sides. 1/3=4/12 because 3x4=12 and 1x4=4.
2/6=4/12 because 6x2=12 and 2x2=4. 9/12+4/12+4/12=17/12, or 1 5/12. You keep the denominator and add the numerators.
        
             
        
        
        
Answer:
3
Step-by-step explanation:
46/5 = 9.2
if you take the reverse of the square which is the square root of 9.2 you get about 3. 
Thus proving that 3 squared times five is infact less then 46.
