Answer:
B. 1 and -2
Explanation:
First, add up the equations:
x-x+3y+y=4
4y=4
y=1
Now, plug y into any of the original equations above and solve for x:
-x+1=3
-x=2
x=-2
Therefore, the answer is B. 1 and -2
Answer:
<em>s= </em>-5.57 (rounded to the nearest hundredth)
Step-by-step explanation:
1. Multiply s and 2 by 7.
You'll get -7s-14. We'll come back to this later
2. Subtract 12 from 37.
You'll get 25
3. Add 14 to both sides so that you cancel out the -14.
The equation stands as -7s= 39
4. Divide both sides by -7 so that we leave <em>s </em>by itself.
s= -5.57142857
Answer: The answer would be B. 
Because we know that she bought 6 bags of 36 jewels. So the first part we would need to solve would be the total number of jewel she purchased. Which would be 
. Then, you must find the total number of jewels that she used. Which would be 
. This means that the equaltion would be the total number of jewels-the total numnber of jewels used. Aka: 
The answer for that would be 434.67. Hope this was helpful pls mark me ans brainliest!!!
