Answer:
3
Step-by-step explanation:
write them out least to greatest- 1 2 3 4 5
then mark out one at a time from front and back- 1 2 3 4 5
then you get one number and that number is 3
I was trying to figure it out but all i got was the meaning of the upside down U. so in the theory of a 9th grader i think...
you would have to distribute A' in to ( C U B)
because with the information i got it has to be in all so by distributing it would be in "all".
being a 9th grader i don't know if this helped but i hope it did just a little! and i deeply apologize if it doesn't.
Answer:
I do know that y = 3 and that x = -2, so any system that has that solution is correct.
Step-by-step explanation:
Multiplying the second equation by -2 and adding the equations will cancel out the x variable. The remaining equation is:
10y = 30. Therefore, y must be 3. Substituting y in for the first equation, we get:
6x + 6 = -6. That means x must be -2. I checked my work with the second equation:
-6 - 12 = -18.
The system results in a true statement, so the answer is y = 3 and x = -2.
