Answer: A trapezoid is always a parallelogram.
Step-by-step explanation:
Hey read the image I have attached. Ignore what I am typing here I need to type 20 characters.
Given that B lies on segment AC and AB=7.8cm , BC = 25mm
Let us convert AB to mm by multiplying with 10 that is AB = 78mm
There are totally 3 possible ways for B lying on segment AC.
Solution 1:- B lies in between A and C,
Then AC = AB+BC
=78+25 = 103 mm
Solution 2:- B lies to the right of C like ACB.
Then AB = AC+CB
78 = AC+25
AC = 78-25 = 53mm
Solution 3:- B lies to the left of A like BAC.
Then BC = BA+AC
25 = 78+AC
Since AC cannot be negative, this way is not possible.
Hence there are only 2 solutions possible.
If we are given that B lies on line joining A and C, then definitely B should lie between A and C. That means nothing but solution 1. So only one solution is possible in this case.
The point of interest is where the graphs cross.
(x, y) = (11, 5)
_____
Linear equations can be solved by any of a variety of methods. Using substitution for y, you have
.. 7x +3(27 -2x) = 92
.. x = 11 . . . . . . . . . . . . . collect terms, subtract 81
Then
.. y = 27 -2*11 = 5
Answer:
The first one or A because 3 times 2 is 6 and 4 times 2 is 8.
