Which expression is equivalent to 10k + 17 - 7j - 18 - 11k?

A. - 8jk - 1 B.-7j - k - 1 C. - 7j + k + 1 D. - 8j - k

B.-7j - k - 1

Step-by-step explanation:

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

Combine like terms

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

-k - 7j - 1

B

Step-by-step 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.
