Answer: The answer is AB = CD.
Step-by-step explanation: We are given a quadrilateral ABCD with AB ║ CD.
We know that a quadrilateral is said to be a parallelogram if any one of the following conditions is satisfied:
(i) If both pairs of opposite angles of a quadrilateral are equal, then it is a parallelogram.
(ii) If one pair of opposite sides of a quadrilateral is both equal and parallel, then it is a parallelogram.
(iii) If the diagonals of a quadrilateral bisect each other, then it is a parallelogram.
We are given that AB is parallel to CD, so by the condition (ii), if we get the additional information that AB = CD, then ABCD will be a parallelogram.
Thus, the answer is AB = CD.
Suppose the one's digit is x, the ten's digit is y. the original number is 10y+x, the reversed number is 10x+y
x+y=13
(10x+y)=(10y+x)-9 =>9y-9x=9 =>y-x=1
Add the two equation to solve: 2y=14 =>y=7
x=13-7=6
the original number is 76.
The mean is <span>29.25 but you need to round it so it would be 30 hope it helps <3</span>
Answer:
370
Step-by-step explanation:
Isolate the numbers so that you are only dividing sections at a time.
So 25 goes in to 92 three times. so we multiply 25 by three and subtract that from 92. Put the three at the top and repeat throughout.
92-75=17
Bring the next number down and repeat.
Answer:
x = 6
Step-by-step explanation:
CT is a median, which means it divided AB into two equal parts so we can write the following equation:
7x + 9 = 5x + 21 transfer like terms to the same side of the equation
7x - 5x = 21 - 9 do the extraction
2x = 12 divide both sides by 2
<u>x = 6</u>
