Answer:
X = 0.6
Step-by-step explanation:
5/2X + 2 = 3.5
subtract 2 from each side
5/2X = 1.5
change 5/2X to 2.5X
2.5X = 1.5
divide both side by 2.5
X = 1.5/2.5
X = 0.6
Answer: That is false

You purchase 4 videos
The original price of each video is x dollars
You decide to purchase the limited edition versions of the videos for an additional cost
Your total cost is (4x + 20) dollars
So, total additional cost is $20
since, we are purchasing 4 videos
so, additional cost in each videos is
So, limited edition cost additional $5 per videos.........Answer
Answer:
(a) isosceles
(b), (c) scalene
Step-by-step explanation:
The lengths of the sides can be found from the distance formula:
d = √((x2 -x1)^2 +(y2 -y1)^2)
Here, there are 9 lengths to be computed, so it is useful to let a spreadsheet or graphing calculator do it.
We find triangle (a) has two sides the same length, so it is isosceles.
The other two triangles have three different side lengths, so they are scalene.
