Answer:
AB is 31.
Step-by-step explanation:
So we know that B is the midpoint of AC. This means that:
by the definition of midpoint.
We know that AB is 2x+1 and BC is 5x-44. Substitute:
Now, find the value of x.
Subtract 1 from both sides:
Subtract 5x from both sides:
Divide both sides by -3:
So, the value of x is 15.
AB is 2x+1.
Substitute 15 into x. So:
Multiply:
Add:
So, the length of AB is 31.
And we're done!
The ratio of the perimeter of the smaller polygon to the larger is 1/3.

Similar figures</h3>
Two figures are said to be similar of they have the same shape and the ratio of their corresponding sides are in the same proportion.
Since the polygons are similar, hence the ratio of their corresponding sides would be congruent. Therefore:
Ratio of smaller polygon to larger polygon = ratio of the perimeter of the smaller polygon to the larger = 3 / 9 = 1/3
The ratio of the perimeter of the smaller polygon to the larger is 1/3.

Answer:
5x -2y = -2
Step-by-step explanation:
-2x+y=0
-7x+3y=2
Subtract the second equation from the first
-2x+y=0
7x-3y=-2
------------------
5x -2y = -2
Answer:
7/12
Step-by-step explanation:
1/3+1/4=7/12
You are basically adding both the fractions
1/3=4/12
1/4=3/12
3/12+4/12=7/12
