43
6
It is: 6 because (6*7)+8 = 50
Let the unknown number be represented by 'n'. Then, (n x 7) + 8 = 50 7n = 50 -8 = 42 n = 42/7 = 6.
You get 50.
47 and 3, 43 and 7, 37 and 13, 31 and 19
To add seven tenths to a number, multiply the number by 1.7. For example, 50 plus seven tenths of 50 is equal to 50 x (1 + (7/10)) = 50 x 1.7 = 85.
Not too sure about your question but let the number be x:- If: 7x+8 = 50 then x works out as 6 But if: 7x = 42+8 then x works out as 7 and 1/7
7 + 15 + 28 = 50
This occurs when you add a negative number. An understanding of negative numbers and their place in the number line is appropriate for this subject. EXAMPLE : 15 + (-7) = 15 - 7 = 8
7.
you add *67 (star 6 7) in front of the number =)
