Each month, Allison gets a $15 allowance and earns $100 working at the theater. She uses the expression 15x + 100y to keep track of her earnings. Part A: Identify the variables and coefficients in the expression. (3 points) Part B: How many terms are in the expression, what are they, and how do you know? (4 points) Part C: Which term in the expression shows the total earned from her allowance? (3 points) (10 points)

yomomalikebracobama:

i dont know any of this-

yomomalikebracobama:

its summer shool we shearch up the awnsers...

Echofire:

In part A, just know that the coefficients are the numbers 'attached' to the left of the variable (which are the letters). For part B, terms are basically a part of an expression. For example, the expression 17x + 76y has 2 two terms if you count it. Lastly, in part C, a big hint would be knowing what Allison's allowance is and which term relates to that. Hopefully this will guide you in the right direction.

yomomalikebracobama:

could u explain part a more

yomomalikebracobama:

@echofire

Echofire:

For which part?

yomomalikebracobama:

In part A, just know that the coefficients are the numbers 'attached' to the left of the variable (which are the letters).

yomomalikebracobama:

woould that be my answer ??

Echofire:

Coefficients are constants, regular numbers, and variables are letters.

yomomalikebracobama:

also the first time i did this two min ago3 questins my teacher gave me a 44 percent

yomomalikebracobama:

so could iput for part a the coefficients are the numbers 'attached' to the left of the variable

Echofire:

You need to say what exactly are the coefficients. Let's say you have y = 2x, the coefficients are 1 and 2, and the variables are x and y.

yomomalikebracobama:

15 and 100?

Echofire:

Would that be the coefficients or variables?

yomomalikebracobama:

doefficients

yomomalikebracobama:

c* lol

Echofire:

Correct!

yomomalikebracobama:

variables aint numbers

yomomalikebracobama:

the coefficients are 15 and 100 attached to the left of the variable that are x and y

Echofire:

Yes, you got it.

yomomalikebracobama:

that would work for part a

yomomalikebracobama:

now part b

yomomalikebracobama:

For part B, terms are basically a part of an expression. the expression 15x + 100y has 2 two terms if you count it.

Echofire:

Yes, you counted correctly.

yomomalikebracobama:

re worded to my question

yomomalikebracobama:

o yea part b is ez

yomomalikebracobama:

i knew that one

Echofire:

Think you got the last one?

yomomalikebracobama:

lemme check

yomomalikebracobama:

Lastly, in part C, a big hint would be knowing what Allison's allowance is and which term relates to that. we know she gets 15x and 100y thats all they gave us

yomomalikebracobama:

i dont get this could u break it down

Echofire:

Remember, her allowance is $15 so see which term relates to those $15.

yomomalikebracobama:

15 can relate with 15

yomomalikebracobama:

x and y an 100

yomomalikebracobama:

cant

Echofire:

You think it is the term with the 15?

yomomalikebracobama:

i dont know ?!?!!?!

Echofire:

$15 and then you have 15x, they seem related.

yomomalikebracobama:

sure do almost like they are the same dam number

Echofire:

That is right.

yomomalikebracobama:

Lastly, in part C, Allison's allowance is 15$ and which term relates to. we know she gets 15x and 100y thats all they gave us

yomomalikebracobama:

but they gave us the fact she gets 100$ and 15$

Echofire:

$15 for allowance and $100 from working.
