Solve your equation step-by-step.
|x|−8=−5
Add 8 to both sides.
|x|−8+8=−5+8
|x|=3
Solve Absolute Value.
|x|=3
We know either x=3 or x=−3
x=3(Possibility 1)
x=−3(Possibility 2)
Answer: either 46 or 25 is your answer

Answer:
Gina is 12 years old
Step-by-step explanation:
First, we will have to write these statements mathematically and then solve.
Let Gina's age be x, let Gina's brother's age be y and let Gina's sister's age be z.
The second statement"Gina's older sister is twice Gina's age" can be mathematically written as: z =2 x ---------------------------(1)
The next statement "Gina's brother is half Gina's age" can be mathematically written as y =
---------------------------------------(2)
Then the next statement "the sum of their ages is 42" can be mathematically written as: x + y + z = 42 ----------------------------(3)
We can now proceed to solve;
Substitute equation (1) and equation(2) into equation (3)
x + y + z = 42
x +
+ 2x = 42
Multiply through by 2
2x + x + 4x = 84
7x = 84
Divide both-side of the equation by 7
= 
x = 12
Therefore, Gina is 12 years old
Answer: The answer is 81.
The third answer option is correct. sqrt(x) = x^(1/2). So sqrt(121) = 121^(1/2).
