Answer:

k = 13

Step-by-step explanation:

The sum of the angles is 180 since they form a straight line

4k-7 + 90 + 3k+6 = 180

Combine like terms

7k+89=180

Subtract 89 from each side

7k+89-89 = 180-89

7k =91

Divide each side by 7

7k/7 = 91/7

k = 13

Answer:

$\dfrac{14}{75}$

Step-by-step explanation:

Gavin made 6 out of 15 shots, so the probability that Gavin's next shot will be successful is

$\dfrac{6}{15}=\dfrac{2}{5}$

Jack made 7 out of 15 shots, so the probability that Jack's next shot will be successful is

$\dfrac{7}{15}$
