Answer:
x = 2, y =7
Step-by-step explanation:
4x - 2y = -6
-6x + 2y = 2
Add the equations together
4x - 2y = -6
-6x + 2y = 2
-----------------------
-2x = -4
Divide each side by -2
-2x/-2 = -4/-2
x = 2
now find y
-6x+2y =2
-6(2) +2y =2
-12+2y =2
Add 12 to each side
-12+12+2y = 2+12
2y =14
Divide by 2
2y/2 =14/2
y =7
In order to compute the markup, compute the percentage like this:
The markup is then $12,32.

Answer:
3:7
Step-by-step explanation:
To find the ratio of the number of votes that were NOT for mayor Jackson, we need to subtract the number of votes that WERE for mayor Jackson to the total number of people that voted in the election.
56,000 - 32,000 = 24,000
So this means that:
24,000 : 56,000
We can simplify this by dividing both sides by 8,000.
24,000 / 8000 = 3
56,000 / 8000 = 7
So we get:
24,000 : 56,000 = 3:7
