Answer:
<2 =67
Step-by-step explanation:
A linear pair adds to 180 degrees
<1 + <2 =180
113+ <2 = 180
<2 = 180-113
<2 =67
4x - 2y = 14
y = 0.5x -1
Get just one variable on one side for both equations.
4x - 2y = 14 ⇒ 4x = 2y + 14 ⇒ 4x - 14 = 2y
y = 0.5x - 1 ⇒ x - 2 = 2y
Use the transitive property and then solve for x.
x-2 = 4x-14
12 = 3x
x = 4
<em>Edit: Apprently I didn't use substitution. Oops! Sorry...</em>
Answer:
the correct answer is 18 - 5i.
Step-by-step explanation:
C. Because you don't need the 0,0 is nothing so it is 121.3
5x+7x+10x-5x =17x
-3-20=-23
Ans: 17x-23
