Answer: 0.06x
Step-by-step explanation:
- An algebraic expression is an expression consist of integer constants, variables, and algebraic operations. 
The given statement:  A number is 30% of 20% of the number x.
The required algebraic expression would be:
30% of 20% of x
 [we divide a percentage by 100 to convert it into decimal]
  [we divide a percentage by 100 to convert it into decimal]

Hence, the required algebraic expression would be :
0.06x
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Juice squeezed from first orange =  = 0.235
 = 0.235
Juice squeezed from second orange =  = 0.3
 = 0.3
Juice squeezed from third orange =  = 0.45
 = 0.45
Juice squeezed from fourth orange =  = 0.27
 = 0.27
Juice squeezed from fifth orange =  = 0.47
 = 0.47 
Total juice squeezed from all the five oranges = 0.235 + 0.3 + 0.45 + 0.27 + 0.47 = 1.725
Total juice to be squeezed = 2 cups
More juice required = 2 - 1.725 = 0.275 
Therefore, to make it 2 cups of orange juice for the family, about  cups of more juice is required.
 cups of more juice is required.
 
        
                    
             
        
        
        
Answer:
x = 8 and y = - 1
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (8, - 1 ) with x- coordinate 8, then
x = 8 ← equation of vertical line
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through
The line passes through (8, - 1 ) with y- coordinate - 1, then
y = - 1 ← equation of horizontal line
