Answer 1

Hi Ashley,

The text, "sum of d and 9", can be represented as (d + 9).

To show 7 times this sum, you would write: 7(d + 9)

The text, "gives 36", would be represented as: 7(d + 9) = 36

If you have to find the value of d, you can solve the equation using the distributive property and inverse operations:

7(d + 9) = 36

7d + 63 = 36

7d + 63 -63 = 36 - 63

7d = -27

7d/7 = -27/7

d = -27

7
