<span>A midpoint divides a line or a segment into two equal parts. If D is the midpoint of the segment AC and C is the midpoint of segment DB, what is the length of the segment AB, if AC = 3 cm.</span>
If D is the midpoint of AC, then AD=DC
If C is the midpoint of DB, then DC=CB
If AC=3cm. then then DC-3/2=1.5
If DC=1.5 then CB is 1.5 also
AB=AC+CB
AB=3+1.5
AB=4.5
Answer:
1,115 mL
Step-by-step explanation:
The original amount of OJ is what we're trying to find, so that will be our variable, x. Now, keep in mind the order of events to write the correct equation. We started with the x amount of OJ, then 240 mL was taken away, to leave us with 875 mL. So, x - 240 = 875. Then we solve this by adding 240 to both sides to get the x alone. This gives us x=1,115 mL!
Answer:
2
Step-by-step explanation:
7+2n = 11
2n = 11-7
2n = 4
n = 4/2
therefore n = 2
Answer:
C.
Step-by-step explanation:
The equation for the slope of a line is y2-y1/x2-x1, and both triangles have the same slope equation for their hypotenuse.
