Question 366832
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
