Question 782018: Solve the Equation
0.5(3x + 0.07) = 20.6
I keep getting high fractions for answers when solving. I do not believe I have the right answer. Can I get help to see if I am doing something wrong or if I am right?
here is my work...
.5(10) (3x + .7)10 20.6(10)
5(30x + 7) = 206
150x + 35 = 206
150x + 35 - 35 = 206 - 35
150x = 171
/150 /150
x = 171/150
This doesn't seem right to me.

Question 783400: I have slept on a waterbed since the 70's. Last year I had to replace the mattress. The waterbed mattress measures 80 inches by 84 inches by 10 inches tall. I filled the matress to capacity with water that I thought was about 92 degrees, but after the bed was filled I found out that the actual temperature was only 74 degrees. It took 3 days for the waterbed heater to warm it up to 92 degrees. I had to sleep on the couch for 3 nights.
One thing that I could have done was drain out part of the water and replace it with 140 degree water. If I had done this, how many gallons of the "colder" water would I have had to drain out of the bed and replace with the 140 degree water, so that the temperature of the bed would have been 92 degrees?
Note: 231 Cubic Inches = 1 Gallon
Soooooo confused on this question. Any help understanding would be great, thank you!

Question 783171: "Solve for y: ((3y+2)/(y-3))=x"
It is not for a graph, just a problem on a worksheet. I wasn't sure if I was supposed to set x equal to zero (which I got y=3 for or to rearrange to get y= -((2-3x)/(3-x))
Those might not even be right...

Question 783331: Sunny was recently sent to a new school in Peach City-Atlanta-GA.. On the first day of her arrival the teacher asked her age and this was Sunny�s curious reply.
�Well, Madam, you see it is like this. At the time I was born, I forgot the year, my only sister Nithya , happened to be just one quarter the age of my mother and she is now one third the age of our father�
�That is very well, Sunanya� said the teacher, but what I asked is not the age of your sister Nithya but your own age�.
Sunanya then replied � Madam, I was just coming to that� and continued � I am just a quarter of my mother�s present age and in four years time I shall be a quarter the age of my father. Is not that funny?
This was all the information that the teacher could get from Sunanaya. Could you work out, from the facts what was Sunanaya�s age? It is certainly little puzzling.
