A
given the 2 equations
2x + y = - 2 → (1)
x + y = 5 → (2)
subtract (2) from (1) term by term to eliminate y
(2x - x ) + (y - y ) = (- 2 - 5 )
x + 0 = - 7 ⇒ x = - 7
substitute x = - 7 in either of the 2 equations and solve for y
(2) : - 7 + y = 5 ( add 7 to both sides )
y = 5 + 7 = 12 → A
 
        
             
        
        
        
Answer:
 94.985in^2
Step-by-step explanation:
Given data
Diameter= 11inches
Radius = 5.5 in i.e 11/2= 5.5inches
The  Area of a circle is given as
Area= πr^2
Substitute
Area= 3.14*5.5^2
Area= 3.14*30.25
Area= 94.985 in^2
Hence the area is 94.985in^2
 
        
             
        
        
        
83 just add the amount of Ella’s and amount of Julio’s
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
We will squared each, we will find 
49/9 5 6.25 8 then the correct order 
Square root 5 
2 1/3 
2.5 
 Square root 8
 
        
             
        
        
        
3/4 = 6/8 = 9/12
4/5 = 8/10 = 12/15
