ANSWER: L=13; W=9 --Please read this explanation and this will be much easier for you, it took time to type.. Set up variables first. I will lead through how to get the answer. First get variables. So, what is Perimeter? Perimeter is like so: P = 2L + 2W = 44ft Now instead of using P, we'll continue with 2L + 2W = 44 because this can be used to help answer the question better than P. "Length of the patio is 5 ft less than twice the width" So it says "length of the patio", so we put L = "5 ft less than twice the width" L = 2W - 5 Now we know what L is, and we can plug this in to our first equation! 2L + 2W = 44 L = 2W - 5 Multiply by 2... 2L = 4W - 10 Plug in... 4W - 10 (2L see?) + 2W = 44 Rearrange... 4W + 2W - 10 = 44 And solve... =6W - 10 = 44 =6W = 44 + 10 =6W = 54 =6W/6 = 54/6 =W = 9 Now we have W. Plug this into our other equation. L = 2W - 5 L = 2*9 - 5 L = 18 - 5 L = 13 The length of the patio is 13 ft and the width of the patio is 9 ft.

Answer:
first you find out how much will 1/2 kg of carrot cost, that way you can multiply it by 3 to get what 3/2 cost.
So, 3÷ 5 = 0.6 per 1/2 kg. Then 0.6 × 3 = 1.8 dollars for 3/2 kg
First you add up all the items and the coupon then you will get $24.51. then subtract $50.00 take away $24.51 then you will get $25.49. So when she left the store she had $25.49
