Answer:
Step-by-step explanation:
N+10
K-15
18*2
6+(2*m)
3*n+8
(5*n)-17
2+(y^2)
(G^4)-9
 
        
             
        
        
        
You can change all of these to decimals and then solve or get common denominators.
8.75 + n + 2.375 + 4.5 = 23.125
15.625 + n = 23.125
Subtract 15.625 from both sides
n = 7.5
        
             
        
        
        
Assuming PQRS is a parallelogram, we have PQ = RS, and angles S and R are supplementary so their measures sum to 180°.
So
5<em>x</em> = <em>x</em> + 12
4<em>x</em> = 12
<em>x</em> = 3
→   PQ = 5<em>x</em> = 15
and
12<em>z </em>° + 6<em>z</em> ° = 180°
18<em>z</em> ° = 180°
<em>z</em> = 180/18 = 10
→   m∠<em>S</em> = 12•10° = 120°
