Hi there!
Let's start by replacing "a number" by the letter "x" so that we can do an equation and isolate "x" to find your answer :
(x -  ) +
) +  = -7
 = -7
subtract  on each side of the equation
 on each side of the equation
x -  = -8.25
 = -8.25
add  on each side of the equation
 on each side of the equation
x = -7.5
-7.5 - 3/4 = -8.25
-8.25 + 5/4 = <u>-7</u>
So your answer is : Three-fourths was subtracted from -7.5, and then 5/4 was added to the result. The sum was -7. 
There you go! I really hope this helped, if there's anything just let me know! :)
 
        
             
        
        
        
All the sides of a cube are always the same. 
Area = 12 in x 12 in = 144 in^2
Volume = 12 in x 12 in x 12 in = 1728 in^3
Hence, you can confirm all the side of this cube is 12 in.
