Answer:
x=3, y=1
Step-by-step explanation:
2x+y =7
3x-4y =5
Multiply the first equation by 4 so we can eliminate y
4(2x+y =7)
8x +4y =28
Add this to the second equation
8x +4y =28
3x-4y =5
----------------
11x = 33
Divide by 11
11x/11=33/11
x=3
Now we still need to find y
2x+y=7
2(3)+y =7
6+y=7
Subtract 6 from each side
6-6+y=7-6
y= 1
Post this again so more people can see it cuz that’s what I do when no one answers my questions
The correct answer is B.
This is because the denominator in this case, would signify be the number of groups.
Answer:
The last choice: x = 3.
Step-by-step explanation:
M < WYX = 1/2 * 78 = 39 degrees ( angle opposite te arc of 78 degrees).
Therefore m < XWY = 180-114-39 = 27 degrees.
7x + 6 = 27
7x = 21
x = 3.
Answer:
I think it’s 105
