Lesson 6-2 Word Problems
... Example 11 We need to rent a large truck for one week. Rental companies charge an initial cost plus an additional cost for each mile driven. One company, Paenz, will rent a 27 foot truck for us for $525 plus $0.21 per mile. Another company, Opan, will rent us the same size truck for $585 plus $0.13 ...

... 7. The poisonous gas hydrogen sulfide, H2S, can be neutralized with a base such as sodium hydroxide, NaOH. The unbalanced equation for this reaction follows: NaOH(aq) + H2S(g) Na2S(aq) + H2O(l) A student who was asked to balance this equation wrote the following: Na2OH(aq) + H2S(g) Na2S(aq) + H3 ...

... Replace x with 17 in the first equation to find y. 17 – y = 12 Subtract 17 from both sides. -y = -5 Divide both sides by –1. y = 5 Replace x with 17 and y with 5 in the second equation to check. 17 + 5 = 22 That is true, so the solution is (17, 5) ...

Partial differential equation
In mathematics, a partial differential equation (PDE) is a differential equation that contains unknown multivariable functions and their partial derivatives. (A special case are ordinary differential equations (ODEs), which deal with functions of a single variable and their derivatives.) PDEs are used to formulate problems involving functions of several variables, and are either solved by hand, or used to create a relevant computer model.PDEs can be used to describe a wide variety of phenomena such as sound, heat, electrostatics, electrodynamics, fluid flow, elasticity, or quantum mechanics. These seemingly distinct physical phenomena can be formalised similarly in terms of PDEs. Just as ordinary differential equations often model one-dimensional dynamical systems, partial differential equations often model multidimensional systems. PDEs find their generalisation in stochastic partial differential equations.
