A fruit company delivers Its fruit in two types of boxes: large and small. A delivery of 3 large boxes and 5 small boxes has a total weight of 90 kilograms. A delivery of 9 large boxes and 7 small boxes has a total weight of 216 kilograms. How much does each type of box weigh?
Weight of each large box: kilogram(s)
Weight of each small box: kilogram(s)

L = large box  S = small box

8L + 3S = 166  Eq (1)

2L + 5S = 67  Eq (2)

Step-by-step explanation:  

A fruit company delivers Its fruit in two types of boxes: large and small. A delivery of 3 large boxes and 5 small boxes has a total weight of 90 kilograms. A

delivery of 9 large boxes and 7 small boxes has a total weight of 216 kilograms. How much does each type of box weigh?

Weight of each large box: kilogram(s)

Weight of each small box: kilogram(s)

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
