evaluate : 4 − 14 ÷ 7 + 32
What do you think you do first?
not sure
1) Parenthesis 2) Exponents 3) Multiplication / Division ( whichever comes first ) 4) Addition / Subtraction ( whichever comes first ) Welcome to Open Study by the way :)
lets look at number 1. Do we have any Parenthesis?
division first
is the amswer 30?
No but you got the first part right. 14 divided by 7 is 2 so 4 - 2 + 32
now in that equation ( 4 - 2 + 32 ) which comes first? Addition or Subtraction?
actaully what i need help on is- Simplify the following expression. 4x − 6y + 2z − 5x − 3y + 8z
ill help you with that after. First tell me the answer of the first one.
well i typed it wrong in the first place
and understand it
Simplify the following expression. 4x − 6y + 2z − 5x − 3y + 8z
|dw:1365534628266:dw|
answer those 3 questions I posted
but how do you combine the like terms?
never mind i see what you did ok hang on
you add letters with letters. you cant add something like 3z + 4y because they dont have the same letters
but you can add 3z + 3z because the variables are the same. It will just give you 6z
-5x + 4x =-1x -6y + -3y =-9y 2z + 8z =10z
great job! so now you just put it out as an equation so you would get -x + -9y + 10z
Thank you very much
