The sum of 200 and 7 times a number can be expressed as the equation (200 + 7x), where (x) represents the unknown number. To find the specific sum, you would need to know the value of (x). Without that information, the expression remains in terms of (x).
the number is 11
21
It is 9*(n + 7)
It could be: (4*11.25)+7 = 52
The answer is 7. Explanation: x+2x=21 therefore 3x=21 so it must be 7
4(7+V)
the number is 11
That number would be 3
It is: 4 times (7+1) = 32
(15+7) +99
21
18
7
It is 9*(n + 7)
It could be: (4*11.25)+7 = 52
The number is 7.
If you add a single number - in this case minus seven - the "sum" is the number itself.
