Umm i don't think you have enough info to answer the question is that one of your choices?
THATS THW WHOLE QUESTION. IM THINKING THE ANSWER IS 18 YEARS OLD.
12+6
Would "12 years plus half of 18" equal to 18?
How about working out:
"12 years plus x/2 equals x"
sorry I don't get it
SALLYS AGE IS 12 YEARS PLUS HALF HER AGE. HOW OLD IS SHE?
The problem is that we don't know Sally's age. All we know is that she is x years old and x equals 12 + x/2.
x = 12 + (1/2)x
(1/2)x = 12
x = 24
To determine Sally's age, we can represent the sentence given as an equation. Let's denote Sally's age as "x." According to the statement, her age is 12 years plus half her age, which can be written as:
x = 12 + (1/2)x
To solve for x, we'll isolate the term with x on one side of the equation. We can start by subtracting (1/2)x from both sides:
x - (1/2)x = 12
Simplifying the left side:
(1 - 1/2)x = 12
Combining the like terms on the left side:
(1/2)x = 12
Now, to get rid of the fraction and solve for x, we can multiply both sides of the equation by 2:
2 * (1/2)x = 2 * 12
The 2's on the left side cancel each other out, leaving:
x = 24
Therefore, Sally is 24 years old.
