Bell Ringer Calculate the average of the following list of numbers What did you do over thanksgiving?
Objective I can solve one step equations. I can find the midpoint of a line.
What are equations? X + 19 = 27 We are trying to solve for X Variable- representing what we are trying to solve for.
To solve: Use the opposite operation to solve: + then use – - then use + (x) or # next to a variable ÷ ÷ or / then use x
Example X – 15 = X + 5 = x= 36 ÷3 ÷3 x/4 = 6 *4 *
Midpoint- the half way point between two points on a line. Half way between 0 and 4 would be 2. Using a formula, how could we calculate this? Midpoint of a line
Midpoint = (x + y ) ÷2 Example (4 + 0) = 4 4 ÷ 2= 2 The midpoint is 2 Midpoint formula
Midpoint with negative numbers Find the Midpoint (2 + -4) = -2 ÷ 2 =-1
