Answer:
x-3y-z
Step-by-step explanation:
separate common terms and add them
1/2x+3/4x=1x
-2y-y=-3y
2z-3z=-1z
1x-3y-1z
 
        
             
        
        
        
Line CA is a straight line, meaning it adds up to 180°
Line BE splits the line into two supplementary angles, because when the two angles are added together they will equal 180°
Using the rule of supplementary angles, we can then make the equation 3x + 8x + 15 = 180
Now, simplify the equation by combining like terms
11x + 15 = 180
To solve, isolate x
11x + 15 = 180
11x = 165
x = 15
        
             
        
        
        
Answer:
A is correct 
Step-by-step explanation:
In this question, we are concerned with. calculating the diameter of a bubble given the volume of the bubble. 
Since we have assumed the bubble to be a perfect sphere, it’s volume V = 4/3 * pi * r^3
Plugging the value of V = 1000cm^3 , we have 
1000 = 4/3 * pi * r^3
3000/4pi = r^3
r^3 = 238.732
r = cube foot of 238.732
r = 6.20cm 
This is same as 6.2cm
