Answer:
Jeb: 50%, Janine: 30%, Arnie: 20%
Step-by-step explanation:
100+60+40=
200 votes in total
1% of 200 = 2
100 divided by 2 = 50
60 divided by 2 = 30
40 divided by 2 = 20
Hope this helps!

Answer: B) -5
Step-by-step explanation: all you do is subtract 12 from each side and you will get -5
Answer:
y=7
Step-by-step explanation:
Assuming that the equation is 14-2y=0
We need to isolate 'y' variable to obtain its value, to do that, lets start by subtracting -14 to both sides of equality sign,
14-2y=0 is now this: 14-14-2y=0-14, which is equals to -2y=-14
Now, lets continue by dividing by -2 both sides of equality sign.
We have this
-2y/-2=-14/-2
y=7
Thus, we've obtained the value for 'y' variable
First thing you should do is reduce coefficients.
1st equation has all multiples of '2'. Divide by 2
---> x +3y = -6
2nd equation has multiples of 5. Divide by 5.
---> x - y = 2
Now elimination part is easier.
Eliminate 'x' variable by subtracting 2nd equation from 1st.
x + 3y = -6
-(x - y = 2)
----------------------
4y = -8
Solve for 'y'
4y = -8
y = (-8)/4 = -2
Substitute value for 'y' back into 2nd equation:
x - (-2) = 2
x + 2 = 2
x = 0
Solution to system is:
x=0, y =-2
