1: verbal phrases to expressions | it is very easy to translate a verbal phrase to an expression. | clue words are the words that tell you to do a certain action or ''operation'' that will help you solve the expression
2: your clue words in the order you have to look for them are is means equal than or from means switch the order per or each means multiply any other clue words | translating verbal phrases into expressions cont. | see if you can translate this verbal phrase into an expression a quotient of a number and 2 equals 20
3: combining like terms. when combining like terms you will have a problem like this 2x(plus)4y(minus)6x so what you will do is first combine your x's (or what ever letter comes first in the alphabet) so it will be 6x minus 2x equals 4x plus 4y now your equation is 4x pules 4y so that would be your equation in it's simplest form. you can not solve it any further unless you are supplied with a variable
4: here are a few more examples of combining like terms 5y minus 6x plus 10y dividedby7 2x times 7y plus 8x divided by 4 6y divided by 9x plus 3y
5: how do you think you did? discuss your answers with the class.
6: do you know the 6 steps to solving an equation? No? Well Here Let me help you. | 1) what is my variable? 2) what is it attached to? 3)by what operation? 4)what's the opposite 5)do the opposite operation to both sides of the equation 5)solve by isolating the variable 6)plug it back in
7: what is my variable? the variable is the unknown letter in your equation. 5 plus x equals 11 x is your variable What is attached? You need to know what number is on the same side of the equal sign. 5 plus x equals 11 5 is attached How is it attached? Now that you have your variable and what is attached, you need to know how it's attached. 5 plus x equals 11 5 is attached by addition You have to do the opposite operation to both sides of the equal sign. 5 plus x equals 11 -5 -5 When you cancel out and subtract, you are isolating the variable. 5+x=10 -5 -5 Xequals6 now check and your done!
8: did you know that there are more than 1 way to solve an equation?
9: 1) use clue words 2) make a table 3) make a movie 4) Draw a picture 5) list your facts
