algebra
did I solve the problem correctly? c=\$200+\$50h c=\$300+\$25h is the answer c=\$250 c=\$325 Do all I have to do to this equation is to add them to get the total cost of labor with h=labor per hour and c=cost or do I have to solve it in a different way. I'm sorry for all the que...

For me to solve the system of equations for the total cost of lawn care using the tequnique substitution am I right to say: c=\$200+\$50h c=\$300+\$25h would be c=\$250 c=\$325

algebra
If my equation that I wrote does it matter how it is written. Does it matter if I write it' \$200+\$50h=c or c=\$200+\$50h or c=\$50h+200

I have a problem with break even analysis? the question is I'm trying to find the cost between 2 businesses to care for my lawn. The one company has an initial fee of \$200+\$50an hour for labor cost and the second company has an initial cost of \$300+\$25an hour for labor cos...

Physics
It is easy to see a drop of water on the print of a glossy magazine but it is difficult to see it on the white area of the same page. Explain why.

Math
y + x = -8 y - x = 4 Use substitution.

Chemistry
oh wait. no. the limiting reactant is CuSO4

Chemistry
So the limiting reactant is aluminum? Thank you so much!

Chemistry
2Al + 3CuSO4 --> + 3Cu + Al2(SO4)3 * copper(II) sulphate is a hydrate 1.2g of CuSo4 50mL of water 1.0 g of aluminum foil What is the limiting reactant?

Physics
Could a simple machine such as a lever, a pulley system or a hydraulic jack be considered a heat engine?
