<h3><em>
40,08791209</em></h3>
Step-by-step explanation:
Multiply first equation by -5 and 2nd by 2, add them
15x+20y=-100
<u>2x-20y=32 +</u>
17x+0y=-68
17x=-68
divide both sides by 17
x=-4
the x value is -4

Step-by-step explanation:
Remark: Not huge
Total number of Socks: 6 + 6 + 4 = 16
P(First Black Sock): 4/16 = 1/4
The second Sock needs to be discussed a bit. The number of black socks has gone down to 1 and the total will always go down by 1.
Second Sock: 3 Black / 15 Total = 3/15 = 1/5
Combined Probability: 1/4 * 1/5 = 1/20
Let A = {Dirk, Johan, Frans, Sarie}, B = {Frans, Sarie, Tina, Klaas, Henrika}, C = {Hans, Frans}. Find the number indicated.

Thank you for posting your question here at brainly. I assume the question should be "<span>Find the number indicated". below is the answers:
</span>B U C means B union C which combines them:
<span>{Frans, Sarie, Tina, Klaas, Henrika, Hans} note that there is no need to write Frans twice. </span>
<span>∩ means intersection which is only what the two sets have in common, in this case: </span>
<span>{Frans, Sarie} </span>
<span>the number is 2. </span>
