Answer:
60
Step-by-step explanation:
Steps to solve "54 is 90 percent of what number?"
We have, 90% × x = 54
or,  
90/100  × x = 54
Multiplying both sides by 100 and dividing both sides by 90,
we have x = 54 ×  100/90  
x = 60
If you are using a calculator, simply enter 54×100÷90, which will give you the answer.
 
        
             
        
        
        
Answer:
x is 11 
Step-by-step explanation:
We know the slope (3/4) and a point (3,-4), so we can use point-slope form (y-y1=m(x-x1) 
Substitute the numbers into the equation 
y--4=3/4(x-3) 
simplify 
y+4=3/4(x-3) 
do the distributive property
y+4=3/4x-9/4 
subtract 4 from both sides
y=3/4x-25/4
this is the equation of the line. 
Since it says that (x,2) is a point in the equation, we can substitute it into the equation
2=3/4x-25/4
add 25/4 to both sides
33/4=3/4x 
multiply by 4/3 
11=x 
we can double check by plugging (11,2) into the equation of the line. 
2=3/4(11)-25/4
2=33/4-25/4
2=2
it works! :) 
Hope this helps!
