Which methods could you use to calculate the x-coordinate of the midpoint of
a horizontal line segment with endpoints at (0,0) and (20, 0)?
Check all that apply.
C. Count by hand
X+x+1+x+2=51
3x+3=51
Use inverse operations to solve
subtract 3 from both sides
3x=48
Divide by 3 on both sides
x=16
16, 17, 18
Answer: 31,948.80
Step-by-step explanation: I thin it his is correct. I multiplied the original amount by .04 then subtracted that from the original number.
<span>A) 11c - 2d = -2
B) c + 8d = 8
</span><span>B) c = 8 - 8d then substitute this into A)
</span><span>A) 88 -88d - 2d = -2
A) 90 = 90d
d = 1
c = 0
