Answer:
x = -6/11
Step-by-step explanation:
-6(-4x + 3) = 2(10x + 3)
-6 * -4x = -24x
-6 * 3 = -18
2 * 10x = 20x
2 * 3 = 6
-24x - 18 = 20x + 6
-20x           -20x
-44x - 18 = 6
+18           +18
-44x = 24
-------   ------ 
  -44      -44
24/-44 = -24/44
-24/44 = -6/22
x = -6/11
 
        
             
        
        
        
The surface area of a sphere is:
A=4πr^2, if r=12 and π is approximated as 3.14 then
A≈4(3.14)(12^2)
A≈4(3.14)(144)
A≈576(3.14)
A≈1808.64 cm^2
        
             
        
        
        
Answer:
x= 4
y= -5
Step-by-step explanation:
-2x+6y=-38    equation 1
3x-4y=32     equation 2
using equation 1 we have:
-2x+6y=-38   
6y +38 = 2x
3y + 19 = x   equation 3
using equation 3 in equation 2 we have:
3(3y + 19) - 4y = 32
9y + 57 -4y =32
5y = 32 -57
5y = -25
y= -25/5
y = -5
so we have:
3y + 19 = x  
3(-5) +19 = x
x= 4
