Answer:

B

Explanation:

We want to simplify the expression. The expression is:

10k + 17 - 7j - 18 - 11k

To simplify this expression, combine the like terms. Add all the terms with a “k”, then the terms with a “j”, and lastly the constants, or terms without a variable.

(10k+ - 11k) + (-7j) + (17+-18)

Add 10k and -11k.

(10k-11k) +(-7j) +(17+-18)

-k+(-7j)+(17+-18)

-k-7j+(17+-18)

There is only one term with a “j”, so we can move on to the constants. Add 17 and -18.

-k-7j+(17-18)

-k-7j-1

The simplified expression is -k-7j-1, which can be rewritten as -7j-k-1. Therefore. B is the correct answer.
