When do you use substitution in real life math problems?
you don't.
How can you use models to compare expressions?
what the heck
Use the substitution method to solve the system of equations Enter your answer as an ordered pair?
Use the substitution method to solve the system of equations. Enter your answer as an ordered pair.y = 2x + 5 x = 1
Why is it important to use order of operations to evaluate algebraic expressions?
I think it is important because you need to know it when you get older.
Why do you use letters in algebraic expressions?
the reason you use letters in algebraic expressions is because you don't know the number so a letter replaces it.

What are some jobs that use algebraic expressions?
A math teacher!
Problems in algebraic expressions?
x+x use inverse operations
What is the difference between algebraic and numerical expressions?
Algebraic expressions use letters as variables to represent numbers. Ex. 5c-(2+x) x=2 c=12 Numerical expressions use numbers only. Ex. 12+(2-7)
Write one numerical expression and one algebraic expression then explain the difference between a numerical and algebraic expression is?
Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.
Simplifying algebraic expressions?
2-9h+6-5n use h=3 and n=2
What is the Real life use of algebraic identities?
They can be used to simplify expressions so that the solutions can be found more easily.
How do you apply a algebraic expressions for daily life?
we use algebraic expressions:for teachingfor cost computingin groceriesfor project evaluationsfor engineeringin architecturein mathematicsin banksfor billingfor manufacturing
What Expressions that use a letter to represent and unknown quantity?
