I did the test and it was 51.4 or 51.5 cuz i submit the test without checking but i got 100% tho
hope i helped^-^
Answer:
.
Step-by-step explanation:
A parallelogram has two pairs of parallel lines so if AD // BC and that AD//BC, Then it is indeed a parallelogram
How many times does 245 go into 8? none.
into 84? none.
into 843? 3
So the first digit of the quotient is 3. Mult. 245 by 3, getting 735. Subtr. this amount from 843. Result: 108. How many times does 245 go into 108?
none. Bring down a zero, forming 1080. How many times does 245 go into 1080? 4, with remainder 100. And so on.
Please try doing this problem yourself, by hand.

245 / 8439.00
-735
----------------
Can you finish this? Note that 843-735 is 108. Bring down a zero now, to form 1080. show your work.
A.9/17 = 0,5294117647058824
B.8/45 = 0,1777777777777778
C.17/9 = 1,888888888888889
D.16/90 = 0,1777777777777778
your answer is B and D
One way to look at it would be to solve for y - if what x is multiplied by is the same for both sides, they're parallel. If one is the negative reciprocal (e.g. for 5/6 the reciprocal is 6/5 and the negative reciprocal is therefore -6/5) of another, they're perpendicular and if they're neither they're neither.Solving for y in x+5y=4, we can subtract x from both sides to get 5y=-x+4. Next, we can divide both sides by 5 to get -x/5+4=y. Since -x/5=(-1/5)(x) and -1/5 is not the negative reciprocal of 5/6 as established earlier, they are neither
