B is the answer I think is correct
Answer:
To know how much he bought it for, let's consider the actual amount it be x.
Step-by-step explanation:
10% of x + $585 = x
x/10 + $585 = x
$585 = x-x/10
$585= 9x/10
9x=$5850
x=$5850/9
x=$650
.: the actual price was $650.
-2x-4 > 8
-2x > 12
x < -6
Wait, what? Why did I reverse the direction of the greater than sign to a less than sign? Well, when you divide a negative number in an inequality problem, you need to reverse the sign. I hope the actual solving is obvious. If it's not, just ask for clarification!
12>10 or 10<12 these would both work. Hope this helps!
These steps include statements B, C, and D. Drawing a line from the segment to any point on the fold line, which is statement A, is not included in these steps because it is not needed. Thus, choice A is not a step in using paper folding to find the midpoint of a line segment.
