Let's say I owe my brother some money (m). As a gift to me, he takes off $2 (Woo Hoo...). Now I owe him $7. How much did I originally owe him?
Since debt is shown with negative numbers, my equation would look like this: m - (-2) = -7
I can change this equation to an addition problem without changing the outcome because subtracting a negative number is the same as adding a positive number.
m + 2 = -7
To solve this, I will need to get m alone on one side of the equal sign. I will do this by subtracting 2 on each side of the equal sign. Now the problem looks like this: m = -9 .
This answer makes sense because if I had originally owed by brother $9 and he took off $2, that means I would only owe him $7.

What is 12 less than g in algebraic expression?
Well, isn't that just a happy little question! To find 12 less than g in algebra, you simply write it as g - 12. See how we gently subtract 12 from g, creating a beautiful expression that captures the essence of mathematical harmony. Just remember, in the world of algebra, there are no mistakes, only opportunities to learn and grow.

2*pi*sqrt(L/g) this expression gives (approximately) the period (in seconds) of a pendulum whose length is L (metres) and g is the acceleration due to gravity = 9.8 metres/second2.
How do you interpret algebraic expressions in terms of their context?
Interpreting algebraic expressions in context involves understanding the real-world situation they represent. This includes identifying the variables, constants, and operations in the expression and linking them to specific quantities or scenarios. For example, in a problem about distance, speed, and time, the expression (d = rt) can be interpreted to mean that distance (d) depends on the rate (r) and time (t). Context helps clarify the meaning of the expression and guides problem-solving by providing relevant information.
Write an expression using a variable?
An expression using a variable could be ( 3x + 5 ), where ( x ) represents a number. In this expression, ( 3x ) indicates three times the value of ( x ), and ( 5 ) is a constant added to it. This type of expression can be used in various mathematical contexts, such as solving equations or modeling real-world situations.
What is a real world representation of a math expression?
A real-world representation of a math expression can be illustrated through budgeting. For example, if a person has a monthly income of $3000 and spends $2000 on expenses, the expression "Income - Expenses" can be represented as "3000 - 2000". This shows how much money remains after expenses, helping the individual understand their financial situation.

What are two methods for solving a real world problem that can be represented by an equation?
Two methods for solving real-world problems represented by equations are graphical and algebraic approaches. The graphical method involves plotting the equation on a coordinate plane to visually identify solutions, such as intersections with axes or other lines. The algebraic method, on the other hand, involves manipulating the equation using algebraic techniques to isolate variables and find numerical solutions. Both methods can provide insights into the problem, allowing for effective decision-making.
How can i select tools to compare quantities in real world situations?
