Answer:
Age of ben = n years
Age of Chloe = 2n years
Age of Dan = (n - 5) years
Now,
Sum of ben, Chloe and Dan's age = t years
or, n +2n + n - 5 = t
or, 4n - 5 =t
This is the required formula
Answer:
Sometimes the best way to tell whether two variables are associated is to ask yourself whether they are not associated. Think backward. In a two-way frequency table, if the relative frequencies for one variable are the same (or close) for all categories of another variable, there is no (or little) associa
Answer:
x=-121
Step-by-step explanation:
.4(5+2x) -12 = .9x+2.1
Distribute the .4
2 + .8x -12 = .9x+2.1
Combine like terms
-10 +.8x = .9x +2.1
Subtract .8x from each side
-10 +.8x-.8x = .9x-.8x +2.1
-10 = .1x +2.1
Subtract 2.1 from each side
-10-2.1 = .1x +2.1-2.1
-12.1 = .1x
Divide by .1
-12.1/.1 = 1.x/.1
-121 =x
