Answer:
x= 56
Step-by-step explanation:
86+94= 180 which if supplementary angles have to equal 180°
I don't know if you can tell but what's in red means distribute
then I added 26 on both sides with like terms
on the left side 86+26=112 and right side is left with 2x
then divide both sides by 2 to leave x by itself
112/2= 56 and 2x/2=x
so 56=x
The midpoint of (x1,y1) and (x2,y2) is

just average them
(4,1) and (-2,4)
the midpoint is

(1,-1.5)
Answer:
20/3
Step-by-step explanation:
Every nth term takes the form of a + n*d, where a is the first term.
So 7th term = (54 = a + 7d), 13th term = (94 = a + 13d).
equate them both:
94 - 13d = 54 - 7d
40 = 6d
d = 40/6
Answer:
B (r= 1/6s)
Step-by-step explanation:
If you just work out each option, you'll see that "s" multiplied by 1/6 gets r.
