Answer:
50=(3x)x
Step-by-step explanation:
50=(3x)x. The question is only asking for the inequality of the problem. Since the area of a rectangle is L x W, you would write L as 3x and W as x, and since the area of the rectangle is given, you can set the area as 50.
 
        
                    
             
        
        
        
Answer:
A.(5,1) to
Step-by-step explanation:
because the y axis is on a 5 and the x axis doesn't have a question ❓⁉️ so you have (A) to be your answer
 
        
             
        
        
        
Answer:
2
Step-by-step explanation:
15x + 16 = 48 - x 
16x = 32
x = 2 
Plug two in and it fits right in :) 
 
        
             
        
        
        
Answer:

Graph in the image attached.
Step-by-step explanation:
Using the model of a linear equation, we have:

'b' is the y-intercept of the equation, that is, the inicial value of G, when D = 0.
So if David starts the trip with 14 gallons of gas, we have b = 14.
'a' is the slope of the line, that is, an increase of 1 in the value of D causes an increase of 'a' in the value of G.
So if the car uses one gallon every 20 miles, the value of a is -1/20 (an increase of 20 in D causes a decrease of 1 in G).]
So our equation is:

The graph of this equation is in the image attached.
 
        
             
        
        
        
The slope intercept form is y=11+2/5x
