Answer:
in order from images displayed, x = 20, x = 6, x = 5.5
Step-by-step explanation:
4x - 8 + 6x - 12 = 180
10x -20 = 180
10x = 200
x = 20
5x - 1 = 29
5x = 30
x = 6
14x - 6 = 12x + 5
2x = 11
x = 5.5
Answer:
20

The slope is -8
Step-by-step explanation:
To find the slope, we can do a very easy equation. We can do the formula
y1 - y2 / x1 - x2
We fit in all of the respective numbers to get the equation as this.
-51-(-75) / 7-10
Then, we get
24/ -3
Simple division gives us -8.
