Answer:
Step-by-step explanation:
First divide 18/45, which equals 2/5 
Then convert 2/5 to a decimal: 0.4
Multiply 0.4 by 100%, which equals 40%
 
        
                    
             
        
        
        
Answer: The value of x is 45
Step-by-step explanation:
The equation x/3-6=9 is a linear equation, where x/3 is the same as one-third of x. 
Thus it is easily simplified as such:
 x/3-6=9 
Collect like terms
 x/3 = 9 + 6
 x/3 = 15
i.e (1/3) of X = 15
To get the value of x, cross multiply 
x = 3 x 15
x = 45
Thus, the value of x is 45

4x-2y=8 ==> y=2x-4 (to better show you what I mean) 
2 lines are parallel if they have the same slope (m the coefficient of x).
So y=mx + b // y =2x-4 means m=2 & y=mx + b, becomes y=2x + b. 
Moreover they are telling us that this function passes by (-2,1), where -2 represents x & 1, represents y. To calculate b , replace x & y by their values:
y=2x+b ==> 1 = 2(- 2) + b==> 1 = -4 + b ==> b= 5. Finally the equation is
y=-2x+5
        
             
        
        
        
If you would like to calculate <span>10÷5/8, you can do this using the following steps:
</span><span>10÷5/8 = (10/5)/8 = 2/8 = 1/4 = 0.25
The correct result would be 1/4 or 0.25.</span>
