Perimeter is the sum of all the sides. So we can set up an equation:
Now solve for 'x', combine like terms:
When it comes to terms with variables it's just like normal addition but we keep the variable:
So we have:
Add:
Subtract 7x to both sides:
Subtract 4 to both sides:
Divide 5 to both sides:
Answer:
When customers wait longer for tables, they are more likely to pay higher prices.
Step-by-step explanation:
Supply/Demand relationships predict that changing one side will influence the other. If demand exceeds capacity, suppliers can raise prices without risk of losing products sold. In fact, total income will rise. The restaurant may raise it's price to the point that supply meets demand. In this case, the goal of the higher priced meals is to reduce wait times, not meals sold. If the meals sold are all at a higher price/meal, then income rises and wait times are reduced. What's not to like, if you own the restaurant?
The expression is written as (4n/9) + 14
What is an expression?
An expression or mathematical expression is a finite collection of symbols that is well-formed according to context-dependent norms. To assist identify the sequence of operations and other features of logical syntax, mathematical symbols can denote numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. Many writers differentiate between an expression and a formula, with the former referring to a mathematical item and the latter referring to a statement about mathematical things. For instance, is a formula. However, in modern mathematics, and particularly in computer algebra, formulae are considered as expressions that may be evaluated as true or false based on the values assigned to the variables in the expressions.
