Step-by-step explanation:
1.n:1
6:8
2.cross multiply
3.8×n÷6×1
8n=6
4 divide both side by 6
=8n÷6=6÷6 :
=8n÷6=1.33...
therefore n=1.33...
“Average rate of change” is the fancy way to say “slope.”
Sketch a graph and put two points with the same y-value, say (2,5) and (7,5).
How much rise is there between those two points? Since they have the same y-value there is no rise at all. You have a horizontal line.
The slope of a horizontal line is 0.
The first answer we see is true the other is based on personal experience
The sum of the inside angles of a 5 sided figure needs to equal 540 degrees.
Add all the angles together to equal 540 and solve for x. Once you have the value for x you can use that to figure out all the angles.
X-8 + 3x-11 + x + 8 + 2x + 7 + x = 540
Simplify by combing like terms:
8x - 4 = 540
Add 4 to both sides:
8x = 544
Divide both sides by 8:
X = 68
Now replace x with 68 in each angle and solve:
U = 68-8 = 60
V = 3(68)-11 = 204-11 = 193
W = 68 + 8 = 76
Y = 68
Z = 2(68) + 7 = 136 + 7 = 143
