0.4(2x+1/2) = 3[0.2x-2]-4
0.8x+0.2 = 0.6x-6-4         Distribute it out
0.8x+0.2 = 0.6x-10          Combine like terms
0.2x = -10.2                     Subtract 0.6x and 0.2 from both sides
x = -51                             Multiply both sides by 5

<span>The Volume of a Cylinder  =   </span><span>π <span>• r² • height<span>
</span></span></span>radius = 13.5 feet
volume = PI * 13.5^2 * 4 feet (the problem states it is to be filled to a depth of 4 feet)
volume = PI * 182.25 * 4
volume = <span> <span> <span> 2,290 cubic feet</span></span></span>
The hose delivers 80 <span>cubic feet per hour so it will take:
</span>2,290 / 80 = <span> <span> <span> 28.625 </span> </span> </span> hours
**************************************************************************
The volume of the pool is:
volume = PI * 182.25 * 4.5
= <span> <span> <span> 2,576.</span></span></span>5 cubic feet

3/10x - 1 = 3/4
Allisa [31]
First you make -1 and 3/4 have a common denominator. 1 has a fraction of 1/1 so times four it is 4/4. Then you add on both sides in order  to isolate x and you get 3/10x = 7/4.

Then you isolate x by multyiplying the reciprocal of 3/10 on both sides, 10/3.
3/10 and 10/3 cancel out and you get an answer of x = 70/4.

You could then simplify it to get 35/6 by finding a greasted common multiple of 12 and 70 which is 2 and dividing both by 2 to get a simpilier answer.

So the answer is x = 35/6
