18 = 10 + 2k
move 10 to the other side
sign changes from +10 to -10
18-10=10-10+2k
18-10= 2k
8= 2k
divide by 2 to get k by itself
8/2= 2k/2
Cross out 2 and 2 , divide by 2 and then becomes 1*1*k= k
k=8/2
Answer: k= 4
In order to prove that this quadrilateral is a parallelogram, we need to get the opposite sides to be parallel.
The answer would be D because it shows 2 triangles to be equal. If they are equal then they must have corresponding sides.
A positive number
This is because you must add to get from a negative number in order to get to a positive number.
Answer:
The slope is -1/2
Step-by-step explanation:
Hope this helps (:
First, divide 2 by 4 which = 0.5
Next, move the decimal point two places over to make 0.5 = 50.0
Then, take 50.0 and add the % sign. This would make = 50%
I hope this helped!
