EFGD is a parallelogram. Find x.A. 1
B. 7
C. 11
D. 6
and,
If ABCD is a parallelogram, what is the length of BD?
A. 10
B. 12
C. 7
D. 5
Answers
Answer:
x = 11
BD = 10
Step-by-step explanation:
Solving for x
The opposite sides if a parallelogram are equal and parallel.
Hence,
2x - 5 = 17
Collecting like terms:
2x = 17 + 5
2x = 22
x = 11
If E is a midpoint, then BE equals to DE
Since BE = 5, then
BD = 2 * BE
BD = 10

Now the equation is:
x - 4/6 + 1/6 = 5/6
So now let's solve for x!
x - 4/6 + 1/6 = 5/6
x + 1/6 = 9/6 (Addition property of equality)
x = 8/6 (Subtraction property of equality)
Now we divide...
8 divided by 6 equals 1.33
Now if we plug that into the equation as 1 and 1/3...
1 and 1/3 - 2/3 + 1/6
2/3 + 1/6
4/6 + 1/6 = 5/6
So that means your answer is decimal 1.33 or mixed fraction 1 and 1/3

I am only in the seventh grade so it might not be right, but this is what I would do:
Set up a proportion: 77/2.194/70.2 = 100/x/y = 240/z/123.9
Then solve for x: if 77 equals 100, that means 2.194 is 77% of x. So x equals 2.849350649
*the 350649 repeats
Then solve for y: Like mentioned before 70.2 is going to only be 77% of y, so if you set that up in a proportion, it is: 70.2/77 = y/100. So when you solve you get 91.16883116883117...
Then finally we solve for z: 100 is only 41.6% of 240, so that means 2.849350649 is only 41.6% of z. So then we set it up as a proportion: 141.6/100 = z/2.849350649, then we solve. It equals 4.034680518984.
Sorry if my answer was redundant, but hope this helped!
