k = 10 - 7

k = 3

Using k = 3 in 9k - 50

(9 * 3) - 50

27 - 50

-23

Answer 2

Answer:

The answer is -23

Step-by-step explanation:

                        k = 10 -7

                          k = 3

                         = 9k - 50                                         (put value of k in it)

                         = 9 (3)-50

                         = 27 - 50

                         = -23
