Write a paragraph proof.
taurus [48]

Step-by-step explanation:

Mid Point :  A point which lies on the line segment and is equidistant from both the ends of the segment is called a mid point.

A line segment can have ONLY ONE mid point and it divides the line segment into two equal parts.

Now, Given : C is the midpoint of AB.

                      and  B is the midpoint of CD.

⇒ AC = BC    and     BC = BD

Now by Euclid's Lemma

- "Things which are equal to the same thing are equal to each other."

Here, AC = BC , and BC = BD

⇒ AC = BD

Hence the result.

Pls help me I don't understand!!!!!!!!
jeka57 [31]

Answer:

X=SMALL BOX.

Y=LARGE BOX

THEREFORE,X+Y=21

X=21-Y

THEREFORE,25(21-Y)+70Y=1110 POUNDS

525-25Y+70Y=1110

525+45Y=1110

45Y=1110-525

45Y=585

Y=585/45

Y=13 .

Therefore,13 large box and8 small box..

2.14 x 6 + 53.87 = y
12.84 + 53.87 = y
66.71 = y
Sooo the predicted height at the time of 6 weeks is 66.71 and then you’d put inches or centimeters or whatever unit after that. :) hope this helps!
