20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50

What characteristics do you find when when corresponding vertices are connected with line segments?
Answer:
D
Step-by-step explanation:
since all x coordinates are distinct, lets just find the x coordinate (multiple choice question)
Midpoint formula:
given two points, (x1, y1) and (x2, y2)
the midpoint is ((x1+x2)/2, (y1+y2)/2)
-3+x2 = 2*2
x2 = 7
Answer: x = 101.75
Step-by-step explanation:
Hi, to answer this question we have to solve the equation give, by isolating x:
8x-4 = 810
The first step is to Add 4 on both sides:
8x-4+4 = 810+4
8x = 814
Then we have to divide both sides by 8:
8x/8 = 814/8
Finally, the solution is:
x = 101.75
