Answer:
x =  20
Step-by-step explanation:
The consecutive angles in a parallelogram are supplementary, sum to 180°
5x + 4x = 180
9x = 180 ( divide both sides by 9 )
x = 20

Step-by-step explanation:
A unit fraction is a fraction that has 1 as it's numerator and a positive number as it's denominator. 
 
        
                    
             
        
        
        
To start, we're given the range that x lies in: from -1 to 4. We know from the fact that 

 that -1 will be <em /><em>included</em> in that range, so we mark -1 on the number line with a solid circle. We also know from 

 that, while x can be any value <em>up to</em> 4, it does not <em>include </em>4. We indicate this by drawing a hollow circle around 4 on the number line. Since x can be <em>any value within this range</em>, we make that fact clear by drawing a bold line between the points -1 and 4 on the number line. I've attached an image of what our final graph would look like.
