Which will solve N in 8xN plus 40 equals?
Nothing will solve an expression. You need an equation (an equality or an inequality) beofre a solution of any kind is possible. Tha means you need something on both sides of the equality (or inequality) sign.
How do you solve b plus 815?
It is not possible to "solve" b+815 because it is an expression - not an equation or inequality.
How would you prove that an inequality does have the same solution that an equation would have?
If you're given the inequality and the equation, then the way to prove that they have the same solution is to solve each one and show that the solutions are the same number. Don't strain yourself, though. An inequality and an equation never have the same solution.
Which inequality has all real number as its solution?
x2 ≥ 0 is one possible answer.
What do the shaded dots refer to in the graph of an inequality?
The shaded area of the graph of an inequality show the solution to the inequality. For example, if the area below y = x is shaded it is showing those ordered pairs which solve y < x.
