Answer:

Step-by-step explanation:
So we have the equation:

First, let's subtract 9 from both sides:

Divide both sides by -4:

Add 1 to both sides:

Divide both sides by 2:

And we're done!
Subtract 8 from both sides
-3x < 15 - 8
Simplify 15 - 8 to 7
-3x < 7
Divide both sides by -3
<u>= x > -7/3</u>

notice the volumes, the cone's volume is really one-third that of the cylinder, assuming "h"eight and "r"adius is the same on both.
Answer:
b) $640
Step-by-step explanation:
Competitor's price = $800
<u>Price, 20% below of competitor's:</u>
- $800 - 20% =
- $800*(100-20)/100 =
- $800*0.8 =
- $640
Correct answer choice is b) $640
you know dam well what 34+35 is...
70-1...
68+1....
aaaaaaaaand im gone bye
