To solve this you can use subtraction
186-27=159 (for the amount Eric gave away)
So Eric has 159 stars left!
Hope this helped!!
        
                    
             
        
        
        
X^2+35=180?
Subtract 35 on each side 
x^2=145
Take the square root 
x= -sqrt(145) 
+sqrt 145...
I hope this helps!!
        
                    
             
        
        
        
Answer:
10.89
Step-by-step explanation:
Circle:
C = TTD
C = TT(6.6)
C = 20.73451151
C = 20.73
Triangle: 
A = bh/2
A = 6.6(3.3)/2        6.6/2=3.3
A = 21.78/2
A = 10.89
Shaded Region = 10.89
 
        
             
        
        
        
Answer:
$837.5
Step-by-step explanation:
Step one:
given data
He makes a guaranteed salary of $400 per week
Commision on top of his base salary equal to 25% of his total sales for the week
Required
His total salary when he made sales of 25%
Step two
let us solve for 25% of $1750 made
=25/100*$1750
=0.25*$1750
=$437.5
Hence his total payment for the week will be 
=$400+$437.5
=$837.5
Also, if the sales is $x his pay would be
let y be his pay
y=0.25x+400
 
        
             
        
        
        
Given that the two triangles are similar:

 =  


 = 

6x + 28 = 4 x 25
6x + 28 = 100
6x = 100 - 28
6x = 72
x = 12
