Do Now www.timessquarenyc.org The New Year’s Eve Ball in Times Square has a diameter of 12 feet and weighs 11,875 lbs. 1)a) Convert 12 feet to inches. b) Convert to yards 2)Convert 11,875 lbs to oz. (reminder 1lb = 16 oz) “The Ball is illuminated by 32,256 Philips Luxeon Rebel LEDs (light emitting diodes). Each LED module contains 48 Philips Luxeon Rebel LEDs 12 red, 12 blue, 12 green, and 12 white for a total of ____ of each color.” Simplify to find out how many of each color are projected. 3) 2 4 4 + 10 3 8 1.) a.) 144 inches b) 4 yds 2.) 190,000 oz 3.) 8,064 LEDs

1/5/2015 6-1 A/D Solve & Write Addition Equations

4
equation- a mathematical statement that 2 expressions are equal Examples: 18 = 10 + 8 144 ÷ 12 = 12 left side right side

5
The goal of solving equations… to get the variable by itself on one side of the equal sign vmlip.wordpress.com

6
Solve 8 = x + 3 Think of this equation as a balanced scale. Whatever you do to one side has to be done to the other to keep it balanced! raggedclothcafe.com

7
8 = x + 3 Write the equation! -3 = -3 Subtract 3 from each side to “undo” the addition of 5 = x 3 on the right side. Ex. 1 Solve 8 = x + 3 5 = x + 0

8
Then check! 8 = x + 3 8 = 5 + 3 8 = 8

9
r + 1.8 = 2.1 Write the equation! - 1.8 = -1.8 Subtract 1.8 from each side to “undo” the addition of r = 0.3 1.8 on the left side. Ex. 2: Solve r + 1.8 = 2.1 r + 0 = 0.3

10
Then check! r + 1.8 = 2.1 0.3 + 1.8 = 2.1 2.1 = 2.1

11
Ex. 3 Then check!

Example 4 Julie and Len went swimming. Julie swam 575 meters. This is 150 more meters than Len swam. Write and solve an addition equation to find the number of meters that Len swam. x + 150 = 575 x = 425 m

13
Exit Ticket: Solve and Check 1) x + 3.6 = 5.31 2) 58 + m = 211 3) 14 = 6 + p 4)n + 12 = 116 5) 1) x = 1.71 2) m = 153 3) 8 = p 4)n = 104 5) 5/8 = j
