In the given equation the value of the x be a x = U*ky-y.
According to the statement
we have to find that the value of the x from the given statement.
So, For this purpose, we know that the 
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
From the given information:
The given statement is 
U=x+y/ky
now, rearrange the terms then
U*ky=x+y
U*ky-y = x
And then the value f the x become 
x = U*ky-y.
So, In the given equation the value of the x be a x = U*ky-y.

Exponentiate the log or In because Exponentials are inverses of Logs and lns.
        
             
        
        
        
V=900m³
V=L*w*h
V=20*3*w
V=60*w
60*w=900
w=900/60
w=15m
        
                    
             
        
        
        
The answer will be D) 75
To find this it’s easiest to find how many animals there are per percent. So to find this you simply have to divide 30 (the number of cats) by 40 (the percent that makes up) to find the number of animals per percent. 
30/40
.75
Then you multiply this by 100 to find how many animals there are total. 
.75(100) 
75
        
                    
             
        
        
        
Step-by-step explanation:
Use the sine and cosine trig functions
21) cos(52)=13/x
x=13/cos(52)
x=21.1
22) sin(75)=6/x
x=6/sin(75)
x=6.2
