A symbol, usually a letter, that represents one or more values of a quantity that changes
Ah, I see. In mathematics, a symbol like a letter that represents one or more values of a quantity that changes is commonly referred to as a variable. Variables are often used to represent unknowns or changing quantities in equations, formulas, and mathematical expressions.
Mario and Luigi plan to buy a Nintendo Switch for $299.00. Nintendo Switch games cost $59.99 each. They plan to purchase one console. Use an algebraic expression to describe how much they will spend, before sales tax, based on purchasing the console and the number of games
Let's represent the number of games they plan on buying as 'g'.
The cost of the Nintendo Switch console is $299.00.
The cost of each game is $59.99.
To calculate the total amount they will spend, we can use the algebraic expression:
Total Cost = Cost of Console + (Number of Games * Cost per Game)
Total Cost = $299.00 + (g * $59.99)
This expression represents their total expenditure, before any sales tax, based on purchasing the console and 'g' number of games.
If they purchase one console and three games, how much will they spend before sales tax?
If they purchase one console and three games, we can substitute 'g' with 3 in the expression:
Total Cost = $299.00 + (3 * $59.99)
Calculating the expression:
Total Cost = $299.00 + ($179.97)
Total Cost = $478.97
So, they will spend $478.97 before sales tax if they purchase one console and three games.
Mario and Luigi want to purchase some extra controllers for their friends. Each controller costs $29.99. Use an algebraic expression to describe how much they will spend in total, before sales tax, based on purchasing the console, the number of games, and the number of extra controllers.
Let's use the following variables to represent the quantities:
- 'c' represents the cost of the console ($299.00)
- 'g' represents the cost of each game ($59.99)
- 'n' represents the number of games
- 'x' represents the cost of each extra controller ($29.99)
- 'e' represents the number of extra controllers
To calculate the total amount they will spend, we can use the algebraic expression:
Total Cost = Cost of Console + (Number of Games * Cost per Game) + (Number of Extra Controllers * Cost per Controller)
Total Cost = c + (g * n) + (x * e)
Therefore, the total expenditure, before any sales tax, based on purchasing the console, the number of games, and the number of extra controllers can be described using the algebraic expression Total Cost = c + (g * n) + (x * e).
What will be the total cost, before sales tax, if Mario and Luigi purchase one console, three games, and two extra controllers?
If Mario and Luigi purchase one console, three games, and two extra controllers, we can substitute the following values into the expression:
c = $299.00 (Cost of Console)
g = $59.99 (Cost of each game)
n = 3 (Number of games)
x = $29.99 (Cost of each extra controller)
e = 2 (Number of extra controllers)
Substituting the values into the expression:
Total Cost = $299.00 + ($59.99 * 3) + ($29.99 * 2)
Calculating the expression:
Total Cost = $299.00 + $179.97 + $59.98
Total Cost = $538.95
So, Mario and Luigi will spend $538.95 before sales tax if they purchase one console, three games, and two extra controllers.

In 1940, most high school students did not go on to college.
The most significant fact that best explains why it is significant that Angelou's narrative is set in 1940 is:
In 1940, segregation of blacks and whites was still the norm.
This is significant because it sets the historical and social context for Angelou's experiences and emphasizes the challenges and adversity she faced as an African American during that time. It allows readers to understand the impact of racial discrimination and inequality on her life and the broader African American community.

Use the diagram to answer the question.
The Hertzsprung-Russell Diagram is shown. The left y-axis is labeled luminosity and the right y-axis is labeled absolute magnitude. The bottom x-axis is labeled with temperature left parenthesis Kelvin right parenthesis. The temperatures along the bottom are 40,000, 20,000, 10,000, 7,500, 5,500, 4,500, and 3,000. The top x-axis is labeled spectral class. The spectral classes labeled along the top from left to right are O, B, A, F, G, K, and M. Spectral class O lines up with a temperature of 40,000 K. Spectral class B lines up with a temperature of 20,000 K. Spectral class A lines up with a temperature of 10,000 K. Spectral class F lines up with a temperature of 7,500 K. Spectral class G lines up with a temperature of 5,500 K. Spectral class K lines up with a temperature of 4,500 K. Spectral class M lines up with a temperature of 3,000 K. Stars of different luminosity, absolute magnitude, spectral classes, and temperatures are plotted on the graph. Red giants and supergiants are shown in the upper right quadrant, indicating lower temperatures. White dwarfs are shown in the lower left quadrant, indicating higher temperatures and lower luminosity. Different main sequence stars are shown, ranging from hot and bright in the upper left quadrant to cooler and dimmer in lower right quadrant.
