Answer:
In x - 5 years.
Step-by-step explanation:
5 years ago:
Sam's age: x
Nina's age: 2x
Now:
Sam's age: x + 5
Nina's age: 2x + 5
Let t be the number of years from now that Nina will be 1.5 times Sam's age.
In t years:
Sam's age: x + t + 5
Nina's age: 2x + t + 5
Nina will be 1.5 times Sam's age:
2x + t + 5 = 1.5(x + t + 5)
2x + t + 5 = (3/2)(x + t + 5)
2(2x + t + 5) = 3(x + t + 5)
4x + 2t + 10 = 3x + 3t + 15
4x + 10 = 3x + t + 15
x - 5 = t
t = x - 5
Answer:
Not a Function
Step-by-step explanation:
A special relationship where each input has a single output.
It is often written as "f(x)" where x is the input value. Example: f(x) = x/2 ("f of x equals x divided by 2"). It is a function because each input "x" has a single output "x/2":

2 3/4 is the same as 44/16
44/16 divided by 3/16 is the same as 44/16 times 16/3
That equals 14 2/3
The answer is 14
Following PEMDAS, we see that the prodcut of x and 5 is 5x, adding two to it would leave 5x + 2
One way is to round the numbers to nearest five. (586 - 321 will be 585-320). Another way is to round it off by tens. (586 - 320 will be 590-320). Hopefully this helps you and god luck!
