1. The width of rectangle is 6cm less than the length. The perimeter is 72cm. Write and solve an equation to find the width an length of a rectangle.
Let W = the width of rectangle in cm
L = the length of rectangle in cm
W = L -6
2L + 2W = 72
2L + 2(L-6) = 72
2L + 2L -12 = 72
4L = 84
L = 21
W = 21-6 = 15
2. Costs for bowling @ a certain bowling alley are $2.50 for shoes and $4.25 for each game bowled. Austin spends $15.25. Write and solve an equation for find how many games he bowled.
Let x = the number of games Austin bowled
2.5 + 4.25x = 15.25
x = 3
