Which algebraic equation best represents the verbal sentence shown? "Seven times the sum of a number and twelve is twenty."
n +84 = 20
0 7(n + 12) = 20
07n + 12 = 20
0 12(n + 7) = 20

7(n+12)=20

Step-by-step explanation:

With these problems I like to work backwards a bit and break each piece down.

Start out with the answer being 20

So, equation=20

Now, look at the "the sum of a number and 12". In terms of an equation, this would be n+12.

The last piece is that n+12 is multiplied by 7.

Thus, 7(n+12)=20
