EE.7 - Solve real-world and mathematical problems by writing and solving equations of the form x + P = Q and PX = Q for cases in which P, Q and X are all non-negative numbers.
warm-up
Solve the Equation Using the Inverse Properties:
1) f + 10 = -2 2) 8 + f = 6 3) f - 5 = -7 4) -8 + f = 8
5) 6f = -12 6) -5f = -25.5 7) f/8 = -4 8) f/-12 = -3
9) 1/2f = 5 10) 2/3f = 2
1) f + 10 = -2 2) 8 + f = 6 3) f - 5 = -7 4) -8 + f = 8
5) 6f = -12 6) -5f = -25.5 7) f/8 = -4 8) f/-12 = -3
9) 1/2f = 5 10) 2/3f = 2

mini lesson - independent work/share out/discussion
Write an equation and show a model for the following problems:
1) Shonna spent $ 52.00 on 3 band T-shirts. If each shirt costs the same amount, how much did she pay for one T-shirt?
2) Jalen received $ 25.00 for babysitting his little brother. He bought a CD for $13.98 and lunch for $5.60. How much money does he have left?
3) Anna and Javon spent $51.00 fixing the tires on their bikes. If Javon spent twice as much money as Anna, how much did each kid spend fixing their bike?
4) If the length of a rectangle is 4 more inches than the width and the perimeter of the rectangle is 72 inches, what are the dimensions of the rectangle?

Morning Walk
Sierra walks her dog Pepper twice a day. Her evening walk is two and a half times as far as her morning walk. At the end of the week she tells her mom, "I walked Pepper for 30 miles this week!." How long is her morning walk?
