Question

max is thinking of a number which she calls n. she adds 8 then doubles the sum.


write an expression to represent maxs number

Answer 1

what is max's final number if her starting number is 7

Answer 2

To represent Max's number \( n \), and considering that she adds 8 and then doubles the sum, we can break it down into steps:

1. Start with the number \( n \).
2. Add 8: \( n + 8 \).
3. Double the result: \( 2(n + 8) \).

Putting it together, the expression that represents Max's operation is:

\[
2(n + 8)
\]

Answer 3

To find Max's final number when her starting number \( n \) is 7, we can substitute \( n \) with 7 in the expression we derived earlier, which is \( 2(n + 8) \).

So, substituting \( n = 7 \):

\[
2(7 + 8)
\]

Calculating inside the parentheses first:

\[
7 + 8 = 15
\]

Now, doubling the result:

\[
2 \times 15 = 30
\]

Thus, Max's final number is **30**.
