Select the choice that translates the following verbal phrase correctly to algebra:

one half of the sum of a number and 10

n/2 + 10

1/2n + 10

n + 10/2

n + 1/2 (10)

Well we have to start with 1/2 of the sum. i will represent sum as s and say i have 1/2 of s and so this is:

1/2 * s

now for the second part "the sum of a number and 10" where number = n

so the sum of n and 10 is:

n + 10

in the first part i represented the sum of the numbers with s and so now i know that:

s = n + 10

plugging this into the top i get

1/2 * (n + 10)

or

1/2n + 1/2 * 10

however i do not see this answer listed but i do not see how it could be wrong

The sum of a number and 10 means:

n+10

And one half of that is:

(n+10) / 2
