Answer:
= 29/12 − -13/6
<span>= ((29 × 6) − (-13 × 12)) / (12 × 6) </span>
= (174 - -156) / 72
= 330/72
= 55/12
<span>= 4 7/12</span>
        
             
        
        
        
Answer:
perimeter = 6x + 15 
Step-by-step explanation:
The perimeter of the triangle is the distance around the triangle.
We need to apply our ability to convert word problems in to mathematical expressions.
We were told that the bottom of the triangle is x units. 
From the diagram perimeter 4x + 12 + x + 3 + x = 6x + 15
Four times the length of the bottom will be 4x .
12 more than 4 times the bottom will be 4x + 12.  
Hence another side of the triangle is 4x + 12.
Finally we were told that the last side is 3 more than the bottom, that will be      x + 3.
 
        
                    
             
        
        
        
-8, -48, -288
or
-8, -4/3, -2/9
        
                    
             
        
        
        
Answer:
<h2>84in²</h2>
Step-by-step explanation:
If the first one is 7 inches long, and 6 inches wide, and the second one is also 7 inches long, but is 6x2 inches wide, then what's the area?
6x2=12
So, Picture Frame 2 = 12 inches wide
Formula for finding area = LxW
L = 7
W = 12
7x12=84
So hence, your answer is 84in²
The area of the second frame is 84in²
 Thanks!
 
        
             
        
        
        
Answer: You determine the coefficient by looking to see if there is a number in front of a variable. If there is a  number in front of the variable, then that is the coefficient. The coefficient is the number, and the variable is the letter. 
Step-by-step explanation: Hope this helps
