All you have to do is divide 3.5 by 5 and you should get 0.7. So she used 0.7 yards on one dress. Hope this helped :)
Answer:
Step-by-step explanation:
One property of parallelogram is that opposite angles have the same measure, so we can write down:
Another property is that two adjacent angles are supplementary (meaning that they add up to 180 degrees). Thus, the following equations are true:
Solve the equations:
To check, add up all 4 angles and check if they sum up to 360 degrees:
And please ignore the fact that I cannot insert the degree sign :(
Here is the answer , and the explanation is written with it .

Step-by-step explanation:
David received 250 votes

1,000 - 250=750
750 - 400 = 350
Answer:
C
Step-by-step explanation:
It is provable about 180 ways, some of them quite elegant. There was a book published in the 1940s listing what they then knew. Others have been added since and it shows up in the oddest places which you can search out.
That is interesting but it does not answer your question.
A: Nothing is defined. This statement is a truth, but unproved. A is not the answer.
B: No term requires defining unless you don't know what a hypotenuse is, but that is a separate problem.
D: a postulate is a statement that is true that cannot be proven nor does it need to be. There aren't that many around in math. Euclid said "All right angles are congruent." True and not needing proof.
C: It is a theorem. This is a statement that may not be obvious and does require proof.
