Add each term and divide it by 2.
5+7 = 12
12/2 = 6
-2 + 6 = 4
4/2 = 2, then add the i back on to get 2i.
The midpoint is 6 + 2i
Answer:
x = 8
Step-by-step explanation:
-10x+6=-74
-10x=-74-6
-10x=-80
x=-80/-10
x=8
2x+4=3x+2
2x=3x-2
-1x=-2
X=2
Hope this helps!
Answer:
You're correct. x= 28
Step-by-step explanation:
2x - 49 + x + 90 + 55 = 180
2x - 49 + x + 145 = 180
3x - 49 + 145 = 180
3x + 96 = 180
3x + 96 - 96 = 180 - 96
3x = 84
3x/3 = 84/3
x= 28
