Answer:
x = 7
Step-by-step explanation:
8x = 56
To solve this, we must simplify. To do this, we must divide each side by 8. This, in term, will give us the value of x.
8x = 56
----    ----
 8       8
56/8 = 7
x = 7
Our answer is x = 7
 
        
             
        
        
        
Answer:
37.5
Step-by-step explanation:
so x% of 40 is 15
the equation for that is 
x/100 * 40 = 15
40x/100 = 15
multiply 100 on both sides
40x = 1500
divide 40 on both sides
37.5
37.5% of 40 is 15
 
        
                    
             
        
        
        
For 3 sides to form a triangle two sides added together need to be greater then the 3rd side. You need to check all 3 combinations:
1. 11.5 + 10.5 = 22, 22> 6.1
 11.5 + 6.1 = 17.6 17.6 > 10.5
 10.5 + 6.1 = 16.6, 16.6 > 11.5
This one can make a triangle.
2. 9.5 + 3.5 > 4.5
 9.5 + 4.5 > 3.5
 4.5 + 3.5 < 9.5
Cannot make a triangle.
3. 8 + 6.7 > 1
 6.7 + 1 < 8
Cannot make a triangle.
4. Can make a triangle
5. Can
6. Can
 
        
             
        
        
        
Number of days that attracted penalty is from April 5 to July 19 which is 105 days.
Thus the amount of simple interest attracted by Ron is given by:
