I've managed other problems like this, but this one has me completely stumped.

Solve the following equations. Find the appropriate values for p and q.

3p - 2q = 37
p + 4q = 3

the values of p and q are the same for each equation, but I can't make it fit.

This is probably elementary, but… If I need to find the value of X after 2 external variables increase it by 29% and 50% respectively. Is the formula simply X(1.29)(1.5)=Y?

I think it was a supernova that I saw the other night. Should I report it? if so, then where? Where can I go to find out if what I say was actually a supernova? Has anyone else ever seen one? How common are they? Any information, links, etc would be appreciated.

this is the question exactly the way it is printed in the book

for a given month, a 300- acre lake has 15 cfs of inflow, 13 cfs of outflow, and a total storage increase of 16 ac-ft. a USGS guage next to the lake recorded a total of 1.3 in of precipitation for the lake for the month. assuming that infiltration loss is insignificant for the lake, determine the evaporation loss, in inches, over the lake for the month.
SOLUTION- solving the water balance for inflow I and outflow O in a lake gives, for evaporation
E = I - O + P - change in S
E= evaporation
I= inflow
O= outflow
P= precipitation
change in S= change in storage

so can anyone help me solve the problem, and/or tell me the best way to set up and work problems similar to this

I dont know how fast the water flows but it would be in a system of underground cinotes.Like in Cancun Mexico. I know that the turbines used on some dams only spin around 180 rpm. What is the minimum speed needed to produce usable current on a 120/240 volt system 3 phase?

Yes, we do, but on our own planet their are animals that don't need it to survive.. So, why do we only looks for planets that have signs of earth like environment when looking for life? I'd have to laugh if we skipped all the planets with stuff on it because it wasn't like earth :)
