Answer:
x=9/4
Step-by-step explanation:
we have:
(4x + 15) = 24
4x=24-15
4x=9
finally: x=9/4
 
        
             
        
        
        
The main property is  as follow
(A^p)^q=A^pxq
so only Sam's work is correct because
(8^4)^5 x(7^3)^9=(8^4x5)x(7^3x9)=8^20x 7^27
        
             
        
        
        
Blue balls : Total number.
Total number of balls = 50 + 45 + 65 = 160
Blue balls : Total number.
= 65: 160    Divide both by 5.
= 13 : 32
= 13/32.    That is the ratio.
        
             
        
        
        
Answer:

Step-by-step explanation:
use y = mx + b where:
y = y-coordinate = 6
m = slope = -1/4
x = x-coordinate = -2
b = y-intercept = what we're solving for to complete the equation
plug the values into the equation
 multiply
               multiply  and 2
 and 2
 subtract
                         subtract  from both sides
 from both sides

now we plug m and b into the equation and leave x and y as variables to get the final equation:

 
        
             
        
        
        
5/14 is the difference between 3/7 and 1/14.
