Answer:
from this table we can tell Y is always 10 times bigger then X so we just have to multiply it again by ten so the answers are
300
500
700
 
        
                    
             
        
        
        
Supplementary angles, when added, equal 180 degrees
so < A + < B = 180...and if < A = 80
     80 + < B = 180
     < B = 180 - 80
    < B = 100 <==
        
                    
             
        
        
        
A cube is a 3d object bounded by  6 square faces. 
Each side of the display case is 3 times longer than the width of the artifact.
width of the artifact = w
side of the cube = 3w
<span>a. Write an expression for the volume of the case.
 volume of a cube is the measure of its side raised to the power of 3.
Volume = (3w)</span>³
<span>Volume = 27w</span>³<span>

You can solve <span>9/x-4/y=8 for x or for y but NOT at the same time.
Solving for x:  </span><span>9/x-4/y=8       Mult all 3 terms by xy to eliminate the fractions.
9(xy)/x - 4xy/y = 8xy         =>       9y - 4x = 8xy, or 9y = 4x + 8xy = 4x(1+2y)
                                                                        then 9y = x [ 4(1+2y) ]
                                                                                     9y
                                                            therefore x = ------------
                                                                                  4(1+2y)
Solve for y using a similar approach.
