Question
15 is the same as the product of 3 and a number. Which equation models this sentence?
15=3x
15=x-3
15=3+x
15=x divided by 3
Answer:
<h2>
15=3x</h2>
Step-by-step explanation:
15 = 3x
x = 15 : 3
x = 5
.........................
check
15 = 3 * 5
15 = 15
the answer is good
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
So, you basically want the equation of the circle.
Given:
Center(C): 

The equation of circle is:

Where,  represents the center point and
 represents the center point and  is the radius of the circle.
 is the radius of the circle.
Plotting the values in the equation:


This is the equation of the circle of center (5, 2) and radius 3.
 
        
             
        
        
        
(50+ b)5
= 5* (50+ b) (commutative property)
= 5* 50+ 5* b (distributive property)
= 250+ 5b
= 5b+ 250
The final answer is 5b+ 250.
Hope it helps.
