Very easy to do this.
60/12 is your fraction.
Multiply numerator and denominator by the same number.
60*2/12*2 = 120/24
120/24 = 5
You can also simplify.
60/12 = 5
12/12 = 1
5/1 = 5
60/12 = 5
 
        
                    
             
        
        
        
Answer: The number is 0.75 or 3/4
Step-by-step explanation:
let x = the number.
Now set up an equation: The product of a number (x) and -4 = -4x. So -4x is subtracted from the number - x.     x-(-4x)
Then, that equals 3 more than the number (x) = x+3
So the equation is x-(-4x)=x+3. 
Then, solve the equation! 
x-(-4x)=x+3
x+4x=x+3  (Distribute the negative to the parentheses)
5x=x+3  (Combine like terms)
4x=3  (Get the Xs on one side by subtracting x from both sides)
x=0.75 or 3/4  (divide by the coefficiant, 4, on both sides)

Answer:
x =20
Step-by-step explanation:
As a line is 180 degrees
So 7x + 40 would be 180, which would lead us with the equation:
7x+40=180
=7x =140 (minus both sides by 40)
=x =20 (divide both sides by 7)
 
        
             
        
        
        
Answer: 
g(5) = 15
Explanation: 
If the x in g(x) is 5 then the x beside 3 would also be 5.
g(5) = 3(5)
g(5) = 15
Hope this helps, good luck!
