Answer:
x = -2
Step-by-step explanation:
Arrange 6x + y= -5, -6x + 12y=96 vertically:
 6x + y= -5
-6x + 12y=96       Now combine like terms:
--------------------
        13y = 91
Solving for y by dividing both sides by 13:  y = 7
Find x by substituting 7 for y in the second equation:  -6x + 12(7) = 96
Then -6x = -84 + 96, or:
-6x = 12, and so x = -2
 
        
             
        
        
        
First, we must figure out how much weight the pig gained and then add that number to the pig’s initial weight. 
To figure out how much weight the pig gained, we must find 30% of 120. 
Because 30% = 0.3, 30% of 120 = 0.3 * 120 ( the word of indicates multiplication in mathematics). 
0.3 * 120 = 36
Therefore, the pig gained 36 pounds. 
To find the pig’s new weight, we must add 36 pounds to the pig’s original 120 pound weight. 
36 + 120 = 156
Therefore, the new weight of Shane’s pig is 156 pounds. 
Hope this helps!
        
             
        
        
        

 = h   Multiply both sides by g to cancel out the fraction
f - 7 = gh   Add 7 to both sides   
  f = gh + 7

Answer:72 tiles
Step-by-step explanation:
16 x 18 = 288ft.2
2 x 2 = 4ft.2
288 divided by 4 = 72 tiles
Since 288 is the space of the wall, each tile has an area of 4 feet squared, so 288 divided by 4 would make it so they need 72 tiles.
