Answer:

the number is 30 ...7x+50+40 = 300

Answer 2

Answer:

Explanation:

Let the required number be x.  

According to the given data, it seems to be a linear equation in x  

Seven times the number gives 7x  

Adding a fifty to that number gives 7x + 50 ____ (1)

To reach a triple century means the above equation needs to be equated to 300  

Still forty is required for it to be equated to 300  

7x + 50 = 300 – 40  

7x +50 + 40 = 300  

7x + 90 = 300  

7x = 300 – 90 = 210  

7x = 210  

x =   = 30
