Tony is four years younger than his brother josh, and two years older than his sister cindy. tony also has a twin brother, evan. all the ages of the children totaled together is 66. how old is tony?

To solve this problem, let us assign the variables. Let us say that:

x = age of Tony = which also the age of his twin brother Evan

x + 4 = age of Josh (since tony is 4 years younger, then josh must be 4 years older)

x – 2 = age of Cindy (since tony is 2 years older, then cindy must be 2 years younger)

There are a total of 4 children, therefore:

x + x + x + 4 + x – 2 = 66

4 x + 2 = 66

4 x = 64

x = 16

Therefore Tony is 16 years old.

The denominator of the fraction goes within the radical symbol. If the denominator is 2, it is not shown, it just uses the radical symbol. The numerator goes underneath the radical. One equivalent expression would be:

3√(x2)
