Supplementary angles measure 180°. Make an equation:

Subtract 28 to leave the variable in the parentheses alone:

Add the 2 x's together:

Your new equation is:

Divide both sides by 2 to leave the variable alone

The supplement measures 76°
 
        
             
        
        
        
Answer:
5y=2
Step-by-step explanation:
8y + 4 = 6 + 2y + 1y
Combine like terms
8y+4 = 6+3y
Subtract 3y from each side
8y-3y+4 = 6+3y-3y
5y +4 = 6
subtract 4 from each side
5y+4-4 = 6-2
5y=2
 
        
                    
             
        
        
        
Answer:
2 real solutions
Step-by-step explanation:
Get all the terms to one side
10n^2 = 10 - 8n
10n^2 +8n -10 =0
ax^2 +bx+c =0
The discriminant is 
b^2 -4ac
8^2 - 4(10)(-10)
64 +400
464
If the discriminant is greater than 0 we have 2 real solutions
 
        
             
        
        
        
Since z is inversely proportional to x, when x increases by a factor of 26/16, z will be multiplied by the inverse of that factor: 16/26
