<span>1. Martina is given to be 14 years older than Joey who is x years old. Hence, the age of Martina can be expressed as,
x + 14
2. If Joey's current age is x then in 5 years he will become x+5 years old.
3. Martina's age will be her current age added with 5 making it, x+14+5 or x + 19.
4. The equation that would best represent the given scenario in this item is:
x + 19 = 3(x + 5)
5. From the given above, the value of x is equal to 2. This is Joey's current age.
6. The current age of Martina is x + 14 which is equal to 16.</span>
Which expression have a value of 16/81? check all that apply. (2/3)^4, (16/3)^4, (4/81)^2, and (4/9)^2
Answer:
First and last option is correct.


Step-by-step explanation:
Given:
There are four options.
(2/3)^4, (16/3)^4, (4/81)^2, and (4/9)^2
We need to check all given options for value of 16/81.

I believe that 7 5/4 is the answer.
To solve for the given problem above:
Let x be the number of boxes left after 3 hours
3 * ½ X = 24
3/2 X = 24
X = 24 * 2/3
X = 16
The correct answer is 16.
