Answer:
−9.333
Step-by-step explanation:
(1): "6.75" was replaced by "(675/100)"
 (675/100)+3/8*x-((13)*1/4)=0 
 Simplify   1/4
 675  3         1
  (———+(—•x))-(13•—)  = 0

5 is the slope and 3 is the y-intercept
        
             
        
        
        
The volume is the product of the height and the area of the base.
  V = Bh
The area of the square base is (4 cm)² = 16 cm², so the height can be found from
  144 cm³ = (16 cm²)h
  h = (144 cm³)/(16 cm² = 9 cm
The height of the prism is 9 cm.

Answer:
The number of the television sets that is model p is 12
Step-by-step explanation:
Here we have total number of television sold = 40
The model p televisions sold for $30 less than the model q televisions
That is $P = $q - $30
Therefore
Let the quantity of the model p sold be X
Let the quantity of the model q sold be X
Therefore
x + y = 40
Total cost of the television = 40 * 141 = $5640
Therefore, 120*x + 90*y = 5640
Plugging in x = 40 - y in the above equation we get
4800 - 30y = 5640 or 
y   = -28 and 
x = 68
If we put y = 40 - x we get
30x + 3600 = 5640  
If we put 
120*x + 150*y = 5640.........(3)
we get
x = 12 and y = 28
Therefore, since the model p sold for $30 less than the model q, from the solution of equation (3) the number of the television sets that is model p = 12
