The length of a rectangle is 1 more than 3 times the width. 5 times the length is 45 more than the perimeter. Find the dimension

Murljashka [212]

Answer:

width = w

length= 3w+1

perimeter= 5(3w+1) -45

perimeter = 2(l+b)

5(3w+1) -45 = 2{(3w+1)+w}

15w - 40 = 8w+2

6w = 42

w =7

therefore width = 7

length= 3w+1 = 22

perimeter= 65

34kurt

Answer:

250 bags

Step-by-step explanation:

Spring 3:7

150:x

3x = 1050

x = 350 bags in spring

Total order = 150 + 350 = 500

Holiday Season 5:5

(5+5)x = 10x = 500

x = 50

5 * 50 = 250 bags
