Answer:
the only value that can be x is option (b) 30.
Step-by-step explanation:
To find the value of x, we need to add all the given numbers and subtract their sum from the given range of 39.
The sum of the given numbers 9+13+18+21+33+46 = 140.
39 = Sum of given numbers + x - 140
Simplifying the equation, we get:
x = 39 + 140 - Sum of given numbers
x = 179 - Sum of given numbers
Now we can check each option to see if it satisfies this equation.
(a) 47:
x = 179 - Sum of given numbers
x = 179 - (9+13+18+21+33+46+47)
x = 179 - 187
x = -8
Since the equation doesn't hold true for option (a), we can eliminate it.
(b) 30:
x = 179 - Sum of given numbers
x = 179 - (9+13+18+21+33+46+30)
x = 179 - 170
x = 9
Since the equation holds true for option (b), 9 can be the value of x.
(c) 7:
x = 179 - Sum of given numbers
x = 179 - (9+13+18+21+33+46+7)
x = 179 - 147
x = 32
Since the equation doesn't hold true for option (c), we can eliminate it.
(d) 8:
x = 179 - Sum of given numbers
x = 179 - (9+13+18+21+33+46+8)
x = 179 - 148
x = 31
Since the equation doesn't hold true for option (d), we can eliminate it.
Therefore, the only value that can be x is option (b) 30.
