Step-by-step explanation:
9x+18 < 9-15
1)9-15= -6
9x+18 < -6
9x+18= -5
9x= (-5) - 18
9x= -23
x= 23/9=2 5/9
X=2,55556
 
        
             
        
        
        
Answer:
Solution given:
y+135°=180°[sum of opposite angle of a cyclic quadrilateral is supplementary]
y=180°-135°
y=25°
again
2x-1+3x+1=180°[sum of opposite angle of a cyclic quadrilateral is supplementary]
5x=180
x=180/5.x=36
<u>x</u><u>=</u><u>3</u><u>6</u><u>°</u><u>,</u><u>y</u><u>=</u><u>2</u><u>5</u><u>°</u>
 
        
             
        
        
        
The value of x is 2 and KNL will be 102

Let the age of devaughn be x and Sydney be y.
Then,x+y=45
x+5=y
y=x+5
here,
put y=x+y in x+y=45
then,
x+y=45
x+x+5=45
2x=40
x=20
now,
y=x+5
y=20+5
y=25
