Answer:
x - 7 = age of whatever you are finding the age of
Step-by-step explanation:
seven years younger implies that you are taking away so we minus it from our variable, Tates age is the variable since it does not tell us his/her age in the statement given.
1. Do a proportion
25.83/x times 52.5/100
2. Do 25.83 times 100 which equals 2,583
3. Do 2,583 divided by 52.5 which equals 49.2
4. Your answer is 49.2
The answer is 2.6666666667
Let's analyse the function

The amplitude is A, so we want A=1.5
Now, we start at x=0, and we have 
After one second, i.e. x=1, we want this sine function to make 330 cycles, i.e. the argument must be 
So, we have

so, the function is

Answer:
x = 10
Step-by-step explanation:
Perimeter of a triangle = the sum of the three sides.
In an isosceles the legs are equal (2x - 6) and the base is x
Perimeter = (x) + (2x - 6) + (2x - 6)
38 = 5x - 12
38 + 12 = 5x
50 = 5x

10 = x
