Answer:
1 and 2 answers are correct
Step-by-step explanation:
2x-y= -8
x-y = -4
ADD BOTH (y is cancelled)
3x= -12
x= -4
-8+y=-8
y=0
-4-y = -4
Multiply all by -1
4+y=4
y=0
X + (x − 2) + (x − 4) = ? ; In which
<span>
x + x </span>− 2 + x − 4 ;
Combine the "like terms" ;
x + x + x = 3x ;
− 2 − 4 = −6 ;
So we have: "3x − 6" as the sum. ;
___________________________
The sum of three consecutive odd integers, in which "x" is the greatest integer; is: "3x − 6" .
_____________________________________________
Note: The three consecutive odd integers, from least to greatest, are:
"(x − 4)" , "(x − 2)" , and "x" .
The sum is: "(3x − 6)<span>" .
</span>_____________________________________________
Note: "(3x − 6)" factors into: " 3(x −2)" .
Note that: " (x − 2) " is the second integer.
______________________________________________
So the sum total, which is: "(3x − 6)" ; is 3 (three) times the value of the second integer; that is, "3 (x − 2)" .

A jar of jelly beans contains 50 red gumballs , 45 yellow gumballs, and 30 green gumballs. You reach into the jar and randomly
select a jelly bean, then select another without
putting the first jelly bean back. What is the
probability that you draw two red jelly beans? This is Dependent because you didnt put the other jelly bean in thus changing the total nmber of jelly beans.

Answer:
Step-by-step explanation:
What i would do is multiply both sides by 2z + 1
so you get z-6=20z+10
-19z=16
z=-16/19
Use order of operations (PEMDAS)
<span>83-<span>(<span>59-<span>(<span>22-18</span>)</span></span>)
</span></span><span><span>83-<span>(<span>59-4</span>)
</span></span></span><span><span>83-55=</span></span>28
Final answer: 28
