Answer:
x=-23
Step-by-step explanation:
Since 180° is a straight line you must find a way to get 180 by adding 97°,106°, and x.
Therefore, x must be equal to -23.
Answer:
P = 15.42 cm
Step-by-step explanation:
Perimeter of circle = (πD/2)+D
Where D = 6 cm
P =( (3.14)(6)/2) + 6
P = (3.14)(3)+6
P = 9.4 + 6
P = 15.4 cm
The answer is not a linear equation and the graph is decreasing. sorry i had made a mistake the first time
It would be 25 because you have to add all the sides around the quadrilateral because you are looking for the perimeter which is adding of all the sides and when you add all the sides you get 25.
First:
2x + 2z = 4
2(x+z)=4
x+z=4/2
x=2-z
-x - y - z= -8
-(2-z)-y-z= -8 replace x
-2+z-y-z= -8 (cancel z)
-2-y= -8
6 = y
Then:
-4x + 4y + 5z = 7 replace x and y
-4(2-z)+4*6 + 5z = 7
-8 + 4z + 24 + 5z = 7
16 + 9z = 7
9z = 7 - 16
9z = -9
z = -9/9
z= -1
Finally
x= 2-z replace z
x = 2- (-1)
x = 3
