Answer: x=+2
Step-by-step explanation:2x-6=12x-26
We move all terms to the left:
2x-6-(12x-26)=0
We get rid of parentheses
2x-12x+26-6=0
We add all the numbers together, and all the variables
-10x+20=0
We move all terms containing x to the left, all other terms to the right
-10x=-20
x=-20/-10
x=+2
Answer:
x=100
Step-by-step explanation:
Since m is parallel to n and p is parallel to q
The construction is missing, so i have attached it.
Answer:
Use the incenter to determine the center to construct the circle.
Step-by-step explanation:
From the attached image, we can see that the 3 bisector of the three interior angles in the triangle intersect at a point. This point is known as the incentre of the triangle.
Now, to draw an inscribed circle inside the triangle, we will draw a perpendicular line from the incentre to any of the 3 sides and we will use the incentre as centre to draw the circle to touch each of the 3 perpendicular points.
Find the nearest numbers that are greater and less that your number, in this case, 7 and 8 which square to 49 and 64 and average them by adding them together and dividing by two.
7+8=15
15/2=7.5
7.5 is the nearest estimated square root of 50 that I can get, but the real answer is about 7.071067811865475. (I used a calculator)

Answers bolded below
Step-by-step explanation:
PAGE 1
20.) 142 + 24 + 2x - 50 = 180 (collect like terms)
116 + 2x = 180 (subtract 116 on both sides)
2x = 64 (divide by 2x on both sides)
x = 32
21.) 40 + 80 + 5m = 180 (collect L.T.'s)
120 + 5m = 180 (subtract 120 on both sides)
5m = 60 (divide by 5 on both sides)
m = 12

10.) <T
11.) CA
12.) ^CAB
13.) UV
14.) m<A = m<T = 66
15.) B, C, A
PAGE 3
16.) ^BAD = ^DCB
17.) ^GFH = ^KJH
18.) x = 7 and y = 8
10x + 65 = 135
10x = 70
x = 7
4y - 4 = 28
4y = 32
y = 8
19.) b = 13 and n = 13
5b - 3 = 62
5b = 65
b = 13
4n - 4 = 48
4n = 52
n = 13
PAGE 4
1.) <A = <D, <B = <E, <C = <F
2.) AB = DE, CB = FE, FD = CA
3.) CAB = FDE, EFD = BCA, BAC = EDF
4.) m<P =105
5.) m<M = 45
6.) m<R = 30
7.) m<N = 30
8.) QR = MN
9.) LN = PR
Hope this helps ya!!
