Answer:

The answer is

$y = - x - 2$

Step-by-step explanation:

The problem is

$x + y = - 2$

First we have to bring x to the other side se we subtract x from both sides

sammy [17]

Answer:

Step-by-step explanation:

Since, In a pack of 52 playing cards, there are 4 jacks in total.

If patricia selects a card at random, then the probability that it will be a jack will be:

Probability it is a jack= $\frac{Total number of jacks}{Total number of cards}$

= $\frac{4}{52}$

= $\frac{1}{13}$

Which is the required probability.
