Can I get some help for me to understand what is the difference between an equation and an expression? Can you solvefor a variable in an expression? Could you explain. Can you solvefor a variable in an equation? Can you explain this to me. Could you give me a phrase or sentence for me to understand?

The techniques for solving linear equations and linear inequalities are similar, yet different. Explain and give an example of both a linear equation and a linear inequality that demonstrates this difference.
1.) Solve and check the linear equation.

2.) Solve and check th

What is the difference between an equation and an expression? Include an example of each. Can you solvefor a variable in an expression? Explain. Can you solvefor a variable in an equation? Explain. Write a mathematical phrase or sentence for your classmates to translate.

Please provide a detailed solution to the attached problem.
Consider the solution of the heat equation for the temperature in a rod of length L=1 with variable diffusivity:
u_t = A^2 d/dx (x^2 du/dx)
The derivatives are partial derivatives.
The boundary conditions are:
u(1,t)=u(2,t)=0
And
u(x,0) = f(x)
sol

Explain how to evaluate an algebraic expression for given values of the variables. How would a person evaluate the expression "3x - 4y + 9" when x = 2 and y = 5?
(i) Explain the difference between a variable, a variable expression, and an equation. (ii) Explain the difference between a constant and a variable. (iii) Explain

Please explain to me how to do this question.
Consider a case where the probability of one object giving the desired result is not 1/2. Suppose you tossed a die (one half of a pair of dice). The probability of six dots coming up is 1/6. Now suppose you tossed the dice. Calculate the probability of only one die showing six dot

Below are examples expressions for a variable. I need to explain my problem and answer just like the examples below, please give me a few problems to explain just like the samples below thanks...
A mathematical expression is similar to a phrase or fragment of a sentence. An expression has no subject and no verb or relatio
