harina [27]

Answer:

Haircuts cost $50.33

Hair Color costs $80.33

Step-by-step explanation:

Let haircut be cost "a"

coloring be cost "b"

2 haircut, 4 coloring equals 422, we can write:

2a + 4b = 422 {Equation 1}

5 haircut, 4 coloring, equals 573, we can write:

5a + 4b = 573 {Equation 2}

We now multiply equation 1 with -1 and add it with Equation 2 to get:

-1(2a + 4b = 422) = -2a - 4b = -422

Now,

-2a - 4b = -422

5a + 4b = 573

----------------------

3a = 151

a = 151/3 = $50.33

Now, to find b, we plug in this value into any equation and solve for b:

2a + 4b = 422

2(50.33) + 4b = 422

4b = 422 - 100.66

b = $80.33

Haircuts cost $50.33

Hair Color costs $80.33

A deck of cards contains 10 black cards and 10 red cards. The first card drawn is not replaced before drawing the second card. W
Virty [35]
<h3>Answer:  9/38</h3>

Reason:

There are 10 red cards out of 10+10 = 20 total.

10/20 = 1/2 is the probability of selecting a red card.

If the red card is not put back (i.e. "no replacement"), then the chances of getting another red card is (10-1)/(20-1) = 9/19

Multiply the two fractions mentioned to get the final answer.

(1/2)*(9/19) = (1*9)/(2*19) = 9/38
