A deck has 52 cards
A deck has 25 black cards.
A deck has 4 "4" cards but 2 of them are black, therefore 2 red
P(black or 4) = (25 + 2) / 52 = 27/52

For g(x)=7x, describe the value of x when g(x)&gt;28.
Stella [2.4K]
If g(x) = 7x, then plug 7x in for g(x) in the inequality.

<span>g(x) > 28
</span><span>7x > 28

To solve this inequality, divide both sides by 7.
7x / 7 = x
28 / 7 = 4

x > 4 when g(x) = 7x and g(x) > 28.
So the answer is x > 4.

Hope this helps!</span>
