Alright so system of eqations: Lets call the amount of chocolate wafer packets (c) and the amount of cheese wafer packets (h) They bought a total of 20 packets so: c + h = 20 They spent $25 dollars, and chocolate packets were $1 while cheese were $2, so: c(1) + h(2) = 25
Do you get it so far?
Alright awesome :) next part, to solve for this, we just use substitution
I think you should try this one out yourself before I give you any answers :P Hint: Solve for h first by making the first equation into c = bla bla bla
Do you want to show me your steps and how you got there or are you in a bit of a rush to get something done?
Alright, so show me step by step what you did and I will guide you in the right direction to the best of my abilities
Remember, you're plugging the first equation into the second equation once you make the first one c = 20 - h
and because you have the variable c in the second equation, you just plug 20- h in as c, and therefore you only have to solve for one variable instead of two making things much easier
x+y=20 2x+5=25 then x=5 y=15
So first thing, always use the given variables, don't change them or you have a lot bigger chance of becoming confused
try again with that in mind
now im confused:(
do i subtract 1 from 2 ?
I'm sorry, I got distracted. Alright I will show you how to do it step-by-step
im now in a rush
c + h = 20 c + 2h = 25 That is our system of equations, now we solve for one variable, then use that value to solve for the other variable: c + h = 20 --> c = 20 - h Using this, we plug it into the second equation: (20 - h) + 2h = 25 --> h = 5 h = 5 back into the first equation, c + 5 = 20, c = 15
If you need me to rewrite everything for you to answer the questions more easily tell me
thanks so much!!!
No problem :) If you have more questions to answer just paste them in here quickly, and I will answer them
Well thank you :D
So whenever you're ready
how old are you?
i dont have anymore, all done(:
I am 16, and you?
same! what part
i am but im doing a "refresher course"
I have to do my own final 4 tests for the second segment of Algebra II Honors however, anytime at all, just ask me and I will respond as fast as I can :)
